Cisco Extension Mobility


The Cisco Extension Mobility feature allows users to temporarily access their Cisco Unified IP Phone configuration such as line appearances, services, and speed dials from other Cisco Unified IP Phones.

Extension mobility functionality extends to most Cisco Unified IP Phones. You can configure each Cisco Unified IP Phone to support Cisco Extension Mobility by using the Default Device Profile window in Cisco Unified Communications Manager Administration (formerly Cisco Unified CallManager Administration). This allows users who do not have a user device profile for a particular Cisco Unified IP Phone to use Cisco Extension Mobility with that phone model.


Note Check the Cisco Unified IP Phone documentation to verify that Cisco Extension Mobility is supported.

Understanding Device Profiles

A device profile defines the attributes of a particular device. A device profile includes information such as the phone template, user locale, subscribed services, and speed dials.

The device profile does not get associated with a physical phone. It includes all the properties of a device except those that are explicitly tied to a device, such as MAC address or directory URL.

When a device profile has been loaded onto a device, the device adopts the attributes of that device profile.

User Device Profile

As system administrator, you configure a user device profile for each individual user. Using the Cisco Unified Communications Manager User Options window, a user can access this profile and make changes, such as adding a service. You can add, modify or delete a user device profile in Cisco Unified Communications Manager Administration.

When a user logs in to a phone that is configured for Cisco Extension Mobility and the user has a user device profile that is configured for that phone, the user device profile replaces the existing configuration of the device.

When a user logs out, the logout profile replaces the user device profile.

Default Device Profile

With Cisco Unified Communications Manager 4.0 or later, you can configure a default device profile for each Cisco Unified IP Phone model that you want to support Cisco Extension Mobility. The phone takes on the default device profile whenever a user logs in to a phone for which that user does not have a user device profile.

A default device profile includes device type (phone model), user locale, phone button template, softkey template, and multilevel precedence and preemption (MLPP) information.

You create a default device profile by using the Default Device Profile Configuration window. A phone can have zero or one default device profile. The maximum number of default device profiles cannot exceed the number of phone models that support Cisco Extension Mobility.

Overview of Cisco Extension Mobility

Cisco Extension Mobility (an XML-based authentication feature) comprises the Cisco Extension Mobility application service and the Cisco Extension Mobility service. You need to activate the Cisco Extension Mobility service from Cisco Unified Serviceability to enable EM.

The Cisco Extension Mobility service runs as an application on the Cisco Tomcat Web Service.

You can activate/deactivate services from Cisco Unified Serviceability > Service Activation. Refer to the Cisco Unified Serviceability Administration Guide for more information.


Note Cisco Extension Mobility works on phones within a single Cisco Unified Communications Manager cluster only.


You can use Cisco Unified Communications Manager Administration to start the Cisco Extension Mobility services (in Cisco Unified Serviceability administration), define how the features will work in your system (using the System Parameters window), and define the phones that will support the feature (using the Default Device Profile window).

As system administrator, you configure a user device profile for each individual user. Using the Cisco Unified Communications Manager User Options window, a user can access this profile and make changes, such as adding a service like Cisco Extension Mobility.

Users access Cisco Extension Mobility by pressing the Services button on a Cisco Unified IP Phone and then entering login information in the form of a Cisco Unified Communications Manager UserID and a Personal Identification Number (PIN). If a user has more than one user device profile, a prompt displays on the phone and asks the user to choose a device profile for use with Cisco Extension Mobility.

When a user logs in, the Cisco Extension Mobility application receives the XML-over-HTTP request for user authentication and verifies the information against the Cisco Unified Communications Manager Directory. (See Figure 1-1.)

Figure 1-1 Cisco Extension Mobility

On authentication, if the login profile matches the login device (that is, the user has a user device profile that is configured for a Cisco Unified IP Phone 7960 and logs into a Cisco Unified IP Phone 7960), Cisco Extension Mobility behaves as follows:

The phone automatically reconfigures with the individual user device profile information.

If the user has one user device profile, the system uses this profile. If the user has more than one user device profile, the user can choose the user device profile that will be used from a list.

The user can access all the services that the user configured on the device profile.

If that same user logs into a Cisco Unified IP Phone where the user does not have a configured user device profile, the login profile will not match the login device on authentication. In this scenario, the system loads the default device profile for that phone model onto the phone, and Cisco Extension Mobility works as described here:

The system copies all device-independent configuration (that is, user hold audio source, user locale, userid, speed dials, and directory number configuration except for the setting "line setting for this device") from the user device profile to the login device.

The system uses the default device profile for that phone model for phone template and softkey template configuration and, if the phone can support addon modules, for the addon module.

If the login device supports feature safe on the phone button template and if the phone template that is configured in the login profile matches the number of buttons, the system uses the phone template from the login profile. Otherwise, the system uses the default device profile for the phone to configure the phone template.

If the phone model supports Cisco Unified IP Phone Services and they are configured, the system copies the services from the user device profile.

If the user device profile does not have Cisco Unified IP Phone Services configured, the system uses the Cisco Unified IP Phone Services that are configured in the default device profile for the login device that is accessed during login. If parameters exist for the subscriber service, the system copies the parameters from the default device profile, and the parameters may not reflect the correct information.

For example, the following scenarios occur when a user who has a user device profile that is configured for Cisco Unified IP Phone 7960 logs in to a Cisco Unified IP Phone 7905, and the default device profile is loaded on the phone.

The user can access the user hold audio source, user locale, userid, speed dials and directory number configuration. The user cannot access phone line setting; the system configured the phone line setting from the default device profile that is configured for the Cisco Unified IP Phone 7905.

The user can access the phone template and the softkey template of the Cisco Unified IP Phone 7905.

The user cannot access an addon module because Cisco Unified IP Phone 7905 does not support it.

The user can access Cisco Unified IP Phone Services if they are configured for the Cisco Unified IP Phone 7905, but the parameters from the subscriber services will reflect the default device profile, not the parameters that the user chose on the User Options window.

Users log out of Cisco Extension Mobility by pressing the Services button and choosing logout. If users do not log out themselves, the system will automatically log them out if you configured the Service Parameters to do so, or the next user of the phone can log out the previous user. After logout, Cisco Unified Communications Manager sends the logout profile to the phone and restarts the phone.

SIP Support for Cisco Extension Mobility

Cisco Extension Mobility supports the following Cisco SIP Unified IP Phones:

7970G/7971G

7961G/41G and 7961GE/41GE (G = Non Gig; GE = Gig)

7911G

Additional Information

See the Related Topics.

Login and Logout Behavior

This section describes how login and logout works from the user perspective. Use this information to respond to questions or problems that users may encounter.

Cisco recommends that you direct your users to log in to their phones at the beginning of the work day. This practice ensures that the user device profile gets loaded on their phone.

If users make changes to their profiles on the Cisco Unified Communications Manager User Options window, the changes will apply the next time that they log in.

The system does not apply the change if the user is already logged in.

If the User Locale that is associated with the login user or profile does not match the locale or device, after a successful login, the phone will perform a restart followed by a reset. This occurs because the phone configuration file gets rebuilt. Addon module mismatches between profile and device may generate the same behavior.

You can establish a time limit, so Cisco Extension Mobility automatically logs out users, after a certain time, throughout the cluster. At the Enforce Maximum Login Time, choose True to specify a maximum time for logins and then set the maximum login time.

See the "Setting the Service Parameters" section.

You can set the service parameter to allow for multiple logins. If you set multiple login not allowed, Cisco Extension Mobility supports only one login at a time for a user. Subsequent logins on other devices will fail until the user logs out on the first device.

If Auto Logout is not enabled and if users forget to log out of a phone, as system administrator, you can log them out. Another user also can log them out when the second user tries to log in to that phone.

If users are logged out of a Cisco Unified IP Phone that has the Cisco Extension Mobility feature configured for it, depending on the logout profile, they may not be able to check voice-messaging systems from that phone until they log in. If they receive a busy signal after pressing the Messages button or any key on the touchtone key pad, they must log in before using the phone.

Users can log in to a phone that is off hook; however, their Cisco Unified IP Phone will not assume their settings until they go on hook. When they go on hook after logging in, their phone will display a "Resetting..." message, and their phone settings will be available from that phone.

The Cisco Extension Mobility profile of a user does not maintain ring type, contrast settings, and volume settings; users configure these settings directly on the Cisco Unified IP Phone.

When a Cisco Extension Mobility user logs out of a device, all Call Back services that are active on the Cisco Extension Mobility user automatically cancel.

Additional Information

See the Related Topics.

Login Call Flow

This section describes the flow of events for the Cisco Extension Mobility login from a system perspective. Understanding the call flow will help you troubleshoot problems that you may have with the feature.

1. A user presses the Services button on the Cisco Unified IP Phone and requests to log in. This action invokes a URL for the Cisco Extension Mobility application.

2. The application determines the URL of the service.

3. The Cisco Extension Mobility application sends a formatted XML/HTTP query to the Cisco Extension Mobility service to determine the state of the phone.

4. The application prompts the user for UserID and PIN. The user enters the UserID and PIN and presses the Submit softkey.

5. The phone performs an HTTP request, and the application tries to authenticate the UserID and PIN.

6. If the UserID and PIN cannot be authenticated, the phone displays "Authentication Error."

If the UserID and PIN are authenticated, the application queries the Cisco Unified Communications Manager Database to get the list of device profiles that are associated with the user.

7. The directory responds with the list of the user device profile(s). If the list has more than one entry, the phone displays the device profiles from which the user can choose.

8. When the user chooses an entry from this list (or if the list has only one entry), the application generates the XML for the service.

9. The application posts, via HTTP, the generated XML login request to the service URL (The application determined the service URL in Step 2).

10. The service responds in a defined XML format to the request with a restart to load the user device profile (that indicates success), or with a failure message.

11. The application returns the correct notification to the device. The phone restarts with the user device profile.

12. In the Phone Configuration window of Cisco Unified Communications Manager Administration, you (the administrator) will see the Current End User Profile and the Current Device Profile, along with links to the applicable End User Profile and Device Profile configuration windows.


Note In the Phone Configuration window, the line number of the device does not change when a user logs in to the phone. It continues to display the line number that is assigned to the phone when no user is logged in.


Additional Information

See the Related Topics.

Logout Call Flow

This section describes the flow of events for the Cisco Extension Mobility logout from a system perspective. Understanding the call flow will help you troubleshoot any problems that you may have with the Cisco Extension Mobility feature.

1. A user presses the Services button on the Cisco Unified IP Phone and requests to log out. This action invokes a URL for the Cisco Extension Mobility application.

2. The application determines the URL of the service.


Note Cisco Extension Mobility looks up the URL in the Cisco Unified Communications Manager Directory on the first instance only; the system then stores the URL as a static variable.


3. The application generates the XML to query the Cisco Extension Mobility service for the current state of the device.

4. The service responds to the application with the current state of device; for example, <userID> is logged in.

5. The application prompts the user to confirm that the user wants to log out.

6. When the user presses the Yes softkey to confirm that the user wants to log out, the application generates XML for the logout operation.

7. The application posts, via HTTP, the generated XML login request to the service URL. (The application determined the service URL in Step 2.)

8. In the case of a successful operation, the phone will restart and load the appropriate device profile. If a failure occurs, a message gets sent to the phone.

9. The application parses the received XML and creates an XML response message.

10. The XML gets returned as a suitable notification to the device, and the phone restarts to load the original user profile or logout profile.

11. In the Phone Configuration window of Cisco Unified Communications Manager Administration, you (the administrator) will no longer see a Current End User Profile and Current Device Profile.


Note In the Phone Configuration window, the line number of the device does not change when a user logs out from the phone. It continues to display the line number that is assigned to the phone when no user is logged in.


Extension Mobility Equivalency

The Cisco Extension Mobility (EM) equivalency enhancement eliminates the phone model dependency of phone button templates. The following factors determine the model equivalency among the various phones:

Various features that the phone models support

Number of buttons that the phone models support

The EM equivalency enhancement introduces the following support feature for the Cisco Unified IP Phones:

Feature Safe on Phone Button Template

Phones can use any phone button template that has the same number of buttons that the phone model supports.

In Release 6.0 of Cisco Unified Communications Manager Administration, be aware that some Cisco Unified IP Phone models (for example, 7970 and 7971) support Feature Safe.

Cisco Unified Communications Manager Administration Configuration Tips

The following sections provide configuration scenarios that use the EM equivalency enhancement.

Configuration Scenario 1

1. Use the User Device Profile Configuration window to create a 7970 user device profile. Name the 7970 user device profile User Profile Test and configure the profile to use the 7970 phone button template and to include the following lines:

DN: 1050, 1051, and 1052

Speed Dial: 5051, 5052, 5053, 5054, and 5055

2. Use the User Configuration window to create a user. Name the user cisco and associate the User Profile Test user device profile with this user.

3. Use the Phone Configuration window to configure a Cisco Unified IP Phone 7970 and a Cisco Unified IP Phone 7971 with extension mobility. Configure each phone to use the Standard phone button template.

4. When the user logs in to a 7970 phone with the User Profile Test user device profile, all the lines (DNs) and speed dials display on the phone screen.

5. When the user logs in to a 7971 phone with the User Profile Test user device profile, because the 7971 phone supports feature safe on the phone button template, all the lines (DNs) and speed dials display on the phone screen.

Configuration Scenario 2

If you configure Cisco Unified IP Phones 7960 and 7961 for extension mobility, notice that these two phone models do not support feature safe. Assuming that you use the standard 7960 phone template for the 7960 default device profile, the 7960 phone displays only the standard 7960 phone template configuration (two lines and four speed dials), regardless of what is configured for the 7961 profile, because the 7960 phone does not support feature safe.

Bulk Administration Tool

You can use the Bulk Administration Tool (BAT) to add and delete several user device profiles for Cisco Extension Mobility at one time. Refer to the Cisco Unified Communications Manager Bulk Administration Guide for more information.

Additional Information

See the Related Topics

Cisco Unified Communications Manager Assistant

A manager who uses Cisco Extension Mobility can simultaneously use Cisco Unified Communications Manager Assistant. The manager logs into the Cisco Unified IP Phone by using Cisco Extension Mobility and then chooses the Cisco IP Manager Assistant service. When the Cisco IP Manager Assistant service starts, the manager can access assistants and all Cisco Unified Communications Manager Assistant features (such as call filtering and Do Not Disturb). For more information about Cisco Unified Communications Manager Assistant, see the Cisco Unified Communications Manager Assistant With Proxy Line Support chapter.

Cisco Unified Communications Manager Attendant Console

If a user logs in to or logs out of the Cisco Unified IP Phone by using Cisco Extension Mobility while logged in to Cisco Unified Communications Manager Attendant Console, the Cisco Unified IP Phone resets, and the call-control status of the attendant console goes down. Cisco Unified Communications Manager Attendant Console displays a message that indicates that the attendant needs to log out and log back in if the directory numbers of the phone have changed. The user must log out of the Cisco Unified Communications Manager Attendant Console. When logging back into the Cisco Unified Communications Manager Attendant Console, the attendant must specify the current directory number of the phone in the Directory Number of Your Phone field of the Settings dialog box.

For more information on entering a directory number in the Cisco Unified Communications Manager Attendant Console, refer to the "Configuring Cisco Unified Communications Manager Attendant Console Settings" section.

Call Display Restrictions

When you enable Call Display Restrictions with Cisco Extension Mobility, Cisco Extension Mobility functions as usual: when a user is logged in to the device, the presentation or restriction of the call information depends on the user device profile that is associated with that user. When the user logs out, the presentation or restriction of the call information depends on the configuration that is defined for that phone type in the Phone Configuration window.

To use Call Display restrictions with Cisco Extension Mobility, you enable the Ignore Presentation Indicators in both the User Device Profile Configuration window (see the "Creating the Device Profile for a User" section) and the Phone Configuration window (see the "Subscribing Cisco Unified IP Phones to Cisco Extension Mobility" on page 23).

For more information about the Call Display Restrictions features, refer to the Call Display Restrictions chapter.

Restrictions

The following restrictions apply to Cisco Extension Mobility:

Cisco Extension Mobility works on phones within a single Cisco Unified Communications Manager cluster only.

The characters that display when a user logs in depend on the current locale of the phone. For example, if the phone is currently in the English locale (based on the Logout profile of the phone), the user can only enter English characters in the UserID.

Cisco Extension Mobility supports a limited number of special characters that can be entered on the phone for the login user ID. These characters include . (period), @, ~, *, &, %, #, +, $, \, the Euro sign, and the pound sterling sign.

If the User Locale that is associated with the login user or profile is not the same as the locale or device, after a successful login, the phone will perform a restart followed by a reset. This occurs because the phone configuration file is being rebuilt. Addon module mismatches between profile and device may have the same behavior.

Cisco Extension Mobility requires a physical Cisco Unified IP Phone for login. Users of office phones that are configured with Cisco Extension Mobility cannot log in to their phones remotely.

When a Cisco Extension Mobility user logs out of a device, all Call Back services that are active on the Cisco Extension Mobility user automatically cancel.

When a migration from Cisco Unified Communications Manager Release 4.x to Cisco Unified Communications Manager Release 6.0 is done, the phones will not display the last login user IDs until users log in for the first time after the migration. When the service parameter "Remember Last Login" gets set to True, Cisco Extension Mobility displays the previous login user ID whenever the user logs in to the phone. This gets done based on a file on the hard disk. For the migration from Release 4.x to Release 6.0, this file does not get migrated to the database; therefore, the user ID of the previous login user will not display.

If Cisco Extension Mobility gets stopped or restarted, the system does not auto log out users who are already logged in after the expiration of logout interval. For those phones, auto-logout happens only once in a day. You can manually log out these users from either the phones or from Cisco Unified Communications Manager Administration.

Standard Extension Mobility (EM) Authentication Proxy Rights specifies both a standard role and a standard user group that are intended for use by applications that interact with Cisco Extension Mobility. Authentication by proxy does not support end-user authentication by proxy. Although you can add an end user to the Standard EM Authentication Proxy Rights user group, that end user does not get authorized to authenticate by proxy.

Cisco Extension Mobility does not support the intercom feature.

When PSIRT (Validate IP Address) is set to true, autologout does not go through the PSIRT validation path. The EM logs show that the phone signs out without PSIRT information. This scenario explains why the user signed out automatically instead of manually signing out.

Installing Cisco Extension Mobility for the First Time

When you install Cisco Unified Communications Manager 4.0 or later, make sure that you also install the Cisco Unified Communications Manager Locale Installer on every server in the cluster. Installing the Locale Installer ensures that you have the latest translated text that is available for user windows and phone displays. For more information, refer to the Cisco Unified Communications Manager Locale Installer documentation.

Now, perform the procedures in the "Configuring Cisco Extension Mobility" section.

Configuring Cisco Extension Mobility

Review the Configuration Guidelines before you configure the feature. If you are unsure how device profiles work, refer to the "Understanding Device Profiles" section. Then, perform the configuration procedures in the sequence that shows in the "Configuration Checklist for Cisco Extension Mobility" section:

Configuration Guidelines

Configuration Example 1

Configuration Example 2

Configuration Checklist for Cisco Extension Mobility

Configuration Guidelines

To avoid problems with deploying Cisco Extension Mobility, be sure to follow these configuration guidelines:

Configure a Default Device Profile for each Cisco Unified IP Phone model in a cluster that you want to support Cisco Extension Mobility.

If you want to enable all phones within a Cisco Unified Communications Manager cluster for Cisco Extension Mobility, do not allow the users to control these phones.

In this scenario, when users go to their Cisco Unified Communications Manager User Options window to change their services, they must choose "Device Profiles" from the "Select a device to configure" drop-down list box. They cannot control an individual phone nor modify the settings for an individual phone.

As administrator, you can change the services for a phone by using Cisco Unified Communications Manager Administration. After making the changes, if you update on the main window (not the popup menu), you must reset the phone for the changes to take effect. This action ensures that the new snapshot gets stored as the logout profile.


Note If the Enterprise Parameter "Synchronization between Auto Device Profile and Phone Configuration" is set to True, the auto device profile automatically updates, and you do not need to update on the main window.


If a particular user controls a device, for example, the user office phone, do not allow anyone else to log in to that device.


Caution The Cisco Extension Mobility feature does not operate properly if you allow users to access the assigned phone of another user.

Additional Information

See the Related Topics.

Configuration Example 1

In a typical Cisco Extension Mobility scenario:

All employees represent users of Cisco Extension Mobility.

All users have a user device profile.

Users do not control individual phones, and they cannot modify settings for an individual phone.

Before a user can use a phone, the user needs to log in.

Users can access common devices, such as lobby phones, conference room phones, and cubicle phones that are meant to be shared.

When users go to their Cisco Unified Communications Manager User Options window to change services or speed dials, they can choose only their device profiles from the "Select a device to configure" drop-down menu. This method ensures that changes that users make to their services will follow them to any Cisco Unified IP Phone after they log in.

Configuration Example 2

In another typical Cisco Extension Mobility scenario

Each user has an assigned phone.

Each user has a device profile that follows the user to every device to which the user logs in.

Each user can access common devices, such as lobby phones, conference room phones, and cubicle phones that are configured to be shared.

In this scenario, no one can use the assigned phone of anyone else.

Adding the Cisco Extension Mobility Service

Add the Cisco Extension Mobility service as a new Cisco Unified IP Phone Service. Configure a name, description, and the URL for the Cisco Extension Mobility service.

To add the Cisco Extension Mobility service, perform the following steps:

Procedure


Step 1 From Cisco Unified Communications Manager Administration, choose Device > Device Settings > Phone Services.

Step 2 Click Add New.

Step 3 At the Service Name field, enter a name for the service.

The user receives this name on the phone when the user presses the Services button. Use a meaningful name; for example, Extension Mobility or EM.

Step 4 Enter the Service URL field as it displays in the following example:

http://<IP Address>:8080/emapp/EMAppServlet?device=#DEVICENAME#

where IP Address of Extension Mobility server specifies the IP Address of the Cisco Unified Communications Manager where Cisco Extension Mobility Application is activated and running.

For example:

http://123.45.67.89:8080/emapp/EMAppServlet?device=#DEVICENAME#


Tip To provide redundancy for the Cisco Unified IP Phone Service, create a Cisco Unified IP Phone Service that uses the host name rather than the IP address. The phone functionality for softkeys and filtering, as well as the phone service, will fail over automatically in the case of a failover.


Step 5 Click Save.


Additional Information

See the Related Topics.

Setting the Service Parameters

Set the Service Parameters to define how the Cisco Extension Mobility service will work across a Cisco Unified Communications Manager cluster. You can use these settings to

Enable and define a maximum login time.

Define the multi-login behavior; that is, whether you allow the user to log in to more than one device at a time.

Enable "remember last user logged in."

Clear call logs (placed, received, and missed calls) during manual Cisco Extension Mobility login and logout. Use the "Clearing call logs" service parameter to clear call logs of a previous user. This ensures privacy and prevents users of the same phone from seeing calls of another user.


Tip Be sure that you activate the Cisco Extension Mobility services before you perform this procedure. You cannot view the service parameters if you did not activate the services. Refer to the Cisco Unified Serviceability Administration Guide for information about using the Cisco Unified Serviceability tool, Service Activation.


To set the Service Parameters for Cisco Extension Mobility, perform the following steps:

Procedure


Step 1 From Cisco Unified Communications Manager Administration, choose System > Service Parameters.

The Service Parameter Configuration window displays.

Step 2 From the Server drop-down menu, choose the server that is running the Cisco Extension Mobility service.

Step 3 From the Service drop-down menu, choose Cisco Extension Mobility.

A new Service Parameter Configuration window displays.

Some of the Extension Mobility service parameters are advanced parameters. Click the Advanced button (magnifying glass) at the top left of the window to expose the advanced service parameters.

Step 4 At the Enforce Maximum Login Time field, choose True to specify a maximum time for logins. After this time, the system automatically logs out the device.

Choosing False means that no maximum time for logins exists.

The default value specifies False.


Tip To set an automatic logout, you must choose True in Step 4 and also specify a system maximum login time in Step 5. Cisco Unified Communications Manager then uses the automatic logout service for all logins.


Step 5 If you specified True at the Maximum Login Time field in Step 4 of this procedure, specify the maximum login time in Hours:Minutes from 0:01 to 168:00 (1 minute to one week).

The default value specifies 8:00 (8 hours).

Step 6 At the Maximum Concurrent Requests field, specify the maximum number of login or logout operations that can occur simultaneously. This number prevents the Cisco Extension Mobility service from consuming excessive system resources. The default value, which specifies 5, addresses most scenarios adequately.

Step 7 At the Multiple Login Behavior field, choose one of the following responses:

Multiple Logins Allowed: A user can log in to more than one device at a time.

Multiple Logins Not Allowed: The second and subsequent login attempts after a user successfully logs in once will fail.

Auto Logout: After a user logs in to a second device, the Cisco Unified Communications Manager automatically logs the user out of the first device.

The default value specifies Multiple Logins Not Allowed.

Step 8 At the Alphanumeric User ID field, choose True to allow the user ID to contain alphanumeric characters. Choosing False allows the user ID to contain only numeric characters.

The default value specifies True.


Note The Alphanumeric User ID parameter applies systemwide. You can have a mix of alphanumeric and numeric user IDs. The system supports only user IDs that can be entered by using the alphanumeric keypad. The case-sensitive userid field requires the characters to be lower case.


Step 9 At the Remember the Last User Logged In field, choose the default value, False.

In a typical hoteling scenario, where users can come into any office and use any phone on a temporary basis, you should set this parameter to False.

A True setting specifies that the extension mobility application remembers the user ID of the last user that logged in to the phone. Use this setting in situations where individuals use their own phone on a regular basis, and no one else uses that phone.

For example, Cisco Extension Mobility could be used to enable the types of calls that are allowed from a phone. Individuals who are not logged in and who are using their office phone can make only internal or emergency calls. But after logging in using Cisco Extension Mobility, the user can make local, long-distance, and international calls. In this scenario, only this user regularly logs in to the phone. It makes sense to set the Cisco Extension Mobility to remember the last user ID that logged in, and you would set the field to True. When the field is set to True, all future logins will cause the user ID of the last successful logged-in user to automatically get filled in and remembered by Cisco Extension Mobility.

Step 10 At the Clear Call Log field, choose True to specify that the call logs are cleared during the Cisco Extension Mobility manual login/logout process.

While a user is using the Cisco Extension Mobility service on an IP phone, all calls (placed, received, or missed) appear in a call log and can be retrieved and seen on the IP phone display. To ensure user privacy by preventing other users of the same phone from seeing the call logs of the previous user, set the Clear Call Log service parameter to True. This ensures that the call logs get cleared when a successful login/logout occurs.


Note Call logs get cleared only during manual Cisco Extension Mobility login/logout. If a Cisco Extension Mobility logout occurs due to an automatic logout or any occurrence other than a manual logout, the call logs do not get cleared.


Step 11 Click Save.

Creating a Default Device Profile for Each Cisco Unified IP Phone Model

Configure a clusterwide default device profile for each model of Cisco Unified IP Phone that you want to support Cisco Extension Mobility. The phone takes on the default device profile whenever a user logs in to a phone model for which the user has no user device profile.

For more information on how Default Device Profiles work, see the "Overview of Cisco Extension Mobility" section.

To add a default device profile for a phone model, perform the following procedure.

Procedure


Step 1 From Cisco Unified Communications Manager Administration, choose Device > Device Settings > Default Device Profile.

The Default Device Profile Configuration window displays.

Step 2 From the Device Profile Type drop-down list box, choose the device (such as a Cisco 7970) to which a profile gets created.

Step 3 Click Next.

Step 4 If applicable, from the Select the device protocol drop-down list box, choose a protocol.

Step 5 Click Next.

Step 6 From the User Hold Audio Source field, choose from the drop-down list box to specify the audio source that plays when a user initiates a hold action.

If you do not choose an audio source, Cisco Unified Communications Manager uses the audio source that is defined in the device pool or, if the device pool does not specify an audio source ID, the system default.


Tip You define audio sources in the Music On Hold Audio Source Configuration window. For access, choose Media Resources > Music On Hold Audio Source.


Step 7 At the User Locale drop-down list box, choose the locale that is associated with the phone user interface.

The user locale identifies a set of detailed information, including language and font, to support users. Cisco Unified Communications Manager makes this field available only for phone models that support localization.


Note If no user locale is specified, Cisco Unified Communications Manager uses the user locale that is associated with the device pool.



Note If the users require information to display (on the phone) in any language other than English, verify that the locale installer is installed before configuring user locale. Refer to the Cisco Unified Communications Manager Locale Installer documentation.


Step 8 At the Phone Button Template field, choose the appropriate phone button template. The phone button template determines the configuration of the phone buttons on Cisco Unified IP Phones.
