The Cisco IP Manager Assistant (IPMA) feature enables managers and their assistants to work together effectively. This feature comprises of a call routing service that enhances the phone capabilities for the manager, and the desktop interfaces for both the manager and the assistant. This service intercepts calls that are made to managers and routes them to selected assistants, managers, or other targets based on preconfigured call filters. The manager can change the call routing dynamically. For example, with a softkey press on the phone, the manager can instruct the service to route all calls to the assistant and can receive status on these calls.

Cisco IP Manager Assistant Service
The information presented in this document is created from devices in a specific lab environment. All of these devices used in this document started with a clear (default) configuration. If you are to work in a live network, ensure that you understand the potential impact of any command before you use it.
These definitions apply within this document:
|Manager||A manager is the user whose incoming calls are intercepted by the routing service and routed appropriately.|
|Assistant||An assistant is a user who handles calls on behalf of a manager.|
|Proxy Line||A proxy line specifies a phone line that appears on the assistant's Cisco IP Phone. You need to configure one proxy line for each manager who is associated with the assistant. Cisco IPMA uses proxy lines to manage calls intended for a manager. If the call-routing software determines that the call should be presented to the assistant because the manager cannot accept the call, the call routes to the proxy line configured for that manager on the assistant's Cisco IP Phone.|
|Intercom Line||A line configured on the manager's and the assistants' phones to allow direct communication between the manager and his or her assistant.|
Refer to Cisco Technical Tips Conventions for more information on document conventions.
The Cisco IPMA route point is assigned a Directory Number (DN), which is then translated to match all Cisco IPMA managers DNs. The service intercepts calls made to the manager's DNs, applies filters configured by either the manager or the assistant, and then routes the call appropriately.
The Cisco Tomcat service loads the Cisco IPMA service. Cisco Tomcat is loaded at the time of Cisco CallManager installation. The Cisco IPMA service performs these tasks:
It hosts the HTTP services that run on the assistant and manager phones.
It hosts the web pages that the assistant and manager use for call control as well as the configuration pages.
It contains the routing logic that applies filters on an incoming call for a manager.
It communicates to a Cisco CallManager cluster through the Cisco CTIManager for Third party call control. Cisco CallManager requires only one Computer Telephony Integration (CTI) connection for all the users in a cluster.
It accesses data from the database and directory.
This document is not intended to describe the configuration process required for Cisco IPMA. The configuration for Cisco IPMA has been well documented.
Refer to Configuring Cisco IPMA for configuration instructions.
Highlights of the configuration steps are listed here.
Set up three partitions: Managers, Cisco IPMA, and Everyone.
Set up two Calling Search Spaces (CSS): CSS-M-E (Managers, Everyone) and CSS-I-E (Cisco IPMA, Everyone).
The DN should be such that it matches the DNs of all managers (such as 50XX)
Partitions should be Cisco IPMA and Everyone
CSS should be CSS-M-E
Softkey template = standard Cisco IPMA manager
Phone button template = standard 7960 (two lines)
Line 1, primary line. Partition = manager, CSS = CSS-I-E
Line 2, incoming intercom line with auto answer, with speaker phone or headset option. Partition = Everyone, CSS-I-E
Speed-dial for intercom line of each configured assistant
User needs to be configured as a manager in the global directory
Softkey template = Standard Cisco IPMA assistant
Phone button template = Cisco IPMA two-line phone button template
Expansion module 1 = Cisco IPMA 14-button template
Line 1, primary line. Partition = Everyone, CSS = CSS-I-E
Add Cisco 14-button extension module 7914 having six lines. Lines 2 to 6 stand as proxy lines for each associated manager
Partition = Everyone, CSS = CSS-M-E
Line 7 on expansion module is configured as the intercom line, with auto answer, with speaker phone or headset option
Partition = Everyone, CSS = CSS-I-E
Speed-dial is configured for the intercom line of each configured manager
Each user needs to be associated with the appropriate manager in the global directory
If a directory search from the Cisco IPMA assistant console is required only on the Cisco CallManager directory, no configuration needs to be done. If another directory needs to be supported, the LDAPConfig.ini file located at C:\Program Files\Cisco\MA\LDAPConfig.ini needs to be modified as appropriate for the LDAP with which you work. Here is a copy of the LDAPConfig.ini file for DC Directory.
##Directory Attributes#### FIRST_NAME=givenname MIDDLE_INITIALS=middleinitial LAST_NAME=sn COMMON_NAME=cn TELEPHONE_NUMBER=telephonenumber USERID=uid DEPARTMENT=departmentNumber ##CONNECTION DETAILS## MAX_DIR_CONNECTION=2 INITIAL_DIR_CONNECTION=2 SEARCHSIZE=25 MAX_TIME_LIMIT=0 SEARCH_CN=false MANAGER_DN=cn=CCM SysUser,ou=Users,o=cisco.com MANAGER_PASSWORD= LDAP_URL=ldap://localhost:8404 SEARCH_BASE=ou=Users,o=cisco.com
The IPMA service redundancy design is a simple active/standby redundancy design. At any point of time, only one server is active and provides service. The other server is in a standby mode that waits to take over if the active server should fail. The standby server monitors the health of the active server by periodically sending an HTTP request for the active state. If this HTTP request fails, the active server is determined to be down, and the standby server now becomes the active server.
The key characteristics of the design are:
There is no failback; once the backup server becomes the active server, it does not revert to become the backup server until it fails.
If a server determines that both servers were down at the same time, all managers and assistants that were logged in before the failure are logged out.
A monitor thread implements a state machine that periodically polls the peer server for its current server state. Based on the current state of this server and of the peer server, the monitor thread determines whether it should remain in its current state or change states.
|Local Service/Peer Service||INIT||ACTIVE||STANDBY||DOWN/UNKNOWN|
|INIT||If primaryServer goActive, otherwise goStandby||goStandby||doNothing (let peer goActive)||goActive|
|ACTIVE||doNothing (let peer goStandby)||If primaryServer doNothing (let peer goStandby) else goStandby||doNothing (this is a steady state)||doNothing (this is a steady state)|
|STANDBY||goActive||doNothing (this is a steady state)||If primaryServer goActive else doNothing (let peer go Active)||doActive|
|DOWN/UNKNOWN||Error (should never get here)||Error (should never get here)||Error (should never get here)||Error (should never get here)|
Cisco IPMA stores various manager and assistant information in the Cisco CallManager SQL database. The purpose of storing data in the SQL database is to preserve the manager/assistant status across client sessions and Cisco IPMA server failovers. In other words, if a manager has set Do Not Disturb (DND) on, when Cisco IPMA fails over to another server, that server must log in the manager and set DND according to the DND status stored in the database. There is no option to set a phone within a hunt group to DND if the user is not available. However, you can use extension mobility in order to allow the user to log in or log off.
When the publisher is down, Cisco IPMA does not honor any requests to modify data maintained in the database. In other words, when the publisher is down, Cisco IPMA does not allow a manager to change his or her DND status.
With Cisco CallManager version 3.3.2, Cisco IPMA stores these informations in the database:
For the manager : WatchOn, DndOn, FilterOn, DivAllOn, FilterType, and SecretKey.
For the assistant : IsAvailable and SecretKey
As a consequence of this, when the publisher (with the primary Cisco IPMA service) goes down, the Cisco IPMA application and the Assistant Console fails over. However, the assistant cannot come online because the application fails to update IsAvailable. This is documented in Cisco bug ID CSCea33623 (registered customers only) - IPMA assistant unable to come online after failover.
With Cisco CallManager version 3.3.3, Cisco IPMA stores less information in the Cisco CallManager SQL database:
For the manager : WatchOn, DndOn, FilterOn, DivAllOn, and FilterType.
For the assistant : none.
As a consequence, the assistant is able to come online in this scenario. However, the manager cannot update any status maintained in the database.
The Do Not Disturb (DND) feature allows you to set your phone to forward calls without ringing the phone. Enable the DND service with the DND soft key on Cisco Unified IP phones that support soft keys. When DND is enabled, inbound calls do not ring the phone, but they do provide visual alerts and call information. They can also be answered if desired
Note: DND is a part of IPMA in Cisco CallManager 4.x and 5.x. In Cisco CallManager 6.x, the DND feature can be used without IPMA. There are several workarounds to use DND in CallManager 4.x and 5.x without IPMA:
In order to use the DND feature without the IPMA service, enable Call Forward All to your voice mail. This forwards all calls to your voice mail without the phone ringing.
Similar to the first workaround, create Speed Dial to Voice Mail, and label it DND on the phone. Whenever you need to switch to the DND mode, press CFwdAll and then the DND speed dial button.
Another simple workaround to implement DND is to use a silent ring tone for the phone.
The Cisco CallManager and Manager Assistant (MA) traces use these identifiers to indicate which softkeys are used. Presently, the softkey event seen in the Cisco CallManager traces differ from the softkey event IDs seen in the MA traces. Fortunately, the IDs in the MA traces correspond to the IDs configured in the softkey template. This is documented in Cisco bug ID CSCdz44718 (registered customers only) .
|Softkey||Call State||Softkey Event ID CM traces||Softkey Event ID CM Template/ MA traces|
|TrnsfVM||Ringing, Connected, OnHold||786500||68|
|ImmDiv||Ringing, Connected, OnHold||786497||65|
When troubleshooting problems with Cisco IPMA, there are checkpoints along the way to determine where a problem occurs. This table shows the steps and where to look for the problem:
|Problem||What to check|
|Services button returns invalid host or nothing.||Check the Services URL entry in Enterprise Parameters.|
|Services button returns 'No services Configured...'||Check that the services for the phone or user profile have been selected.|
|To set up speed dials and other services for your phones..."||Check that the services for the phone or user profile have been selected.|
|Phone displays "Host not Found".||Cisco Tomcat service may be stopped.|
|Phone displays "Initialization in progress. Please try again later".||Cisco Tomcat is starting. Allow the service to fully start before trying to log into Cisco IPMA.|
|During the attempt to transfer to voicemail, the "That Key is not active error message is displayed.||
Check if these are configured correctly:
|When you try to add a second line to the intercom line space in the IPMA configuration, the Error Updating device and line(s) information. Unknown Error error message is received.||Uncheck the Automatic Configuration and update the User Configuration.|
|After a restart of CTI and IPMA service on servers in the Cisco CallManager cluster, some of IPMA assistants lost their speed dials.||Refer to Troubleshoot Missing Speed Dials Issue In IPMA for more information on how to resolve this issue.|
|Assistant Console displays the Cisco IPMA Error A system Failure was found, please contact your system administrator. error message.||Under the Service Parameter for IPMA assistant, makes sure that the IP address for the CTI Manager is entered. Then, restart the Cisco Tomcat service and CTIManager service.|
|IPMA console hangs on login due to file version check.||Make sure that the firewall does not block the port 8080.|
|IPMA assistant console issue, the users account does not open and the System error.Please contact administrator error message appears.||Restart the Cisco Tomcat and IPMA service.|
The Filtering down error message appears in the IP Phone in which IPMA configuration is not used presently and this prevents you from making and receiving calls on the IP Phone.
This message appears because the IPMA was possibly misconfigured and later the configuration was not removed properly from the IP Phone. So, as a resolution to the problem, remove IPMA properly and modify the service parameters. Make sure that IPMA service is Stopped in the TomCat.
When you access the IPMA application, the SYSTEM ERROR PLEASE CONTACT ADMINISTRATOR error message appears.
Complete these steps in order to resolve the issue:
Make sure that The Manager and assistant phones are not associated with multiple users
You need to restart these services out of production hours:
Cisco IP Manager Assistant
Note: ChooseCisco Unified Serviceability > Tools > Control Center - Feature Services and choose the Subscriber. Then choose the previous services services and restart it one by one. Then choose the Publisher and choose the previous services and restart it one by one.
Issue the utils service restart Cisco Tomcat command in order to restart Tomcat service from the CLI.
Note: This command needs to be applied on the Subscriber only.
You are unable to connect to IPMA service from assistant console and the http 503 error appears. The HTTP 503 error indicates a web issue that is related to tomcat service.
When you attempt to restart the Tomcat service, this error message appears that indicated an issue with CTI Manager:
Message from syslogd@FAURDEFRA01VS02 at Wed Jun 29 20:52:23 2011 ... FAURDEFRA01VS02 local7 0 : 4: Jun 29 18:52:23.20 UTC : %CCM_TOMCAT_APPS-JAVAAPPLICATIONS-0-IPMANotStarted: IPMA Application not started Servlet Name:Cisco IP Manager Assistant Reason:Service failed to go active. Provider is not a super provider App ID:Cisco Tomcat Cluster ID: Node ID:FAURDEFRA01VS02
This issue occurs because the CTIManager is not configured on the IPMA service parameter. Choose Cisco Unified Serviceability > Tools > Control Center - Feature Services on CUCM and restart the Cisco CTIManager in order to resolve this issue.
The user receives the voicemail prompt and enters the PIN to log on but nothing happens. The filtering screen window appears on the IP phone whenever the user calls the voicemail. This issue occurs after the CUCM upgrade.
This issues arises due to the phone service that does not run on the assistant IP phone.
If you submit HTTP Get requests through a windows browser by typing the specific URL in the address bar, the exact XML returned by the service may be examined. The URL is generally the URL defined for the IP phone service.
Note: The device name is a necessary parameter for all such requests.
The format for such a request is as follows:
Where #DEVICENAME# = SEPmac_address. This is an example:
Refer to Troubleshooting Features and Services for more troubleshooting information.
Cisco IPMA server trace files can be found on the IPMA server at these locations:
C:\Program Files\Cisco\Tomcat\jvm.stderr and jvm.stdout
Go to the service parameters for Cisco IPMA on the Cisco CallManager server to enable debug tracing.
In MA traces, the string "accepted call" is the start of the call, as shown in this example:
