Revised October 12, 2007

This document provides instructions for integrating the Ericsson MD-110 phone system with Cisco Unity by using the Intel NetStructure PBX-IP Media Gateway (PIMG) and an RS-232 serial cable.

Integration Tasks

Before doing the following tasks to integrate Cisco Unity with the Ericsson MD-110 phone system by using the Intel NetStructure PBX-IP Media Gateway (PIMG), confirm that the Cisco Unity server is ready for the integration by completing the applicable tasks in the applicable Cisco Unity installation guide.

The following task lists describe the process for creating the integration.

Task List to Create the Integration

Use the following task list to set up a new integration with the Ericsson MD-110 phone system. If you are installing a new Cisco Unity server by using the applicable Cisco Unity installation guide, you may have already completed some of the following tasks.

1. Review the system and equipment requirements to confirm that all phone system and Cisco Unity server requirements have been met. See the "Requirements" section.

2. Plan how the voice messaging ports will be used by Cisco Unity. See the "Planning How the Voice Messaging Ports Will Be Used by Cisco Unity" section.

3. Program the Ericsson MD-110 phone system and extensions. See the "Programming the Ericsson MD-110 Phone System" section.

4. Set up the PIMG units. See the "Setting Up the PIMG Units" section.

5. Create the integration. See the "Creating a New Integration with the Ericsson MD-110 Phone System" section.


Caution Do not edit the phone configuration file (also known as the switch ini file) to customize this integration. If you change the settings in this file, the integration may not function correctly.

6. Test the integration. See the "Testing the Integration" section.

7. (Cisco Unity 4.1 and later) If you have a secondary server for Cisco Unity failover, integrate the secondary server. See the "Integrating a Secondary Server for Cisco Unity Failover" section.

Requirements

The Ericsson MD-110 integration supports configurations of the following components:

Phone System

Ericsson MD-110.

Software level BC6 or later.

ICU card installed to provide the serial data port.

One or more of the applicable PIMG units. For details, refer to the "Supported Circuit-Switched Phone System Integrations" section in the applicable Supported Hardware and Software, and Support Policies at http://www.cisco.com/en/US/products/sw/voicesw/ps2237/prod_installation_guides_list.html.

The serial data port on the phone system connected to the serial port on the master PIMG unit with an RS-232 serial cable.

We recommend that the serial cable have the following construction:

A maximum of 50 feet (15.24 m) in length

24 AWG stranded conductors

Low capacitance—for example, no more than 12 pF/ft (39.4 pF/m) between conductors

At least 65 percent braided shield over aluminized polymer sleeve around conductors

UL-recognized overall cable jacket insulation with low dielectric constant

Braided shield fully terminated to and enclosed by a metal connector backshell

Gold-plated connector contacts

The voice messaging ports in the phone system connected by analog lines to the ports on the PIMG units.

We recommend that you connect the voice messaging ports on the phone system to the ports on the PIMG units in a planned manner to simplify troubleshooting. For example, the first phone system voice messaging port connects to the first port on the first PIMG unit, the second phone system voice messaging port connects to the second port on the first PIMG unit, and so on.

The PIMG units connected to the same LAN or WAN that Cisco Unity is connected to.

If the PIMG units connect to a WAN, the requirements for the WAN network connections are:

For G.729a codec formatting, a minimum of 32.76 Kbps guaranteed bandwidth for each voice messaging port.


Caution If you use G.729a codec formatting over a WAN and your PIMG units use firmware release 4 SU6 or earlier, you must disable comfort noise. Otherwise, callers will hear loud comfort noise at certain points. For details, see the "Appendix: PIMG Integrations Over a WAN That Use the G.729a Codec May Need to Disable Comfort Noise" section.

For G.711 codec formatting, a minimum of 91.56 Kbps guaranteed bandwidth for each voice messaging port.

No network devices that implement network address translation (NAT).

A maximum 200 ms network latency.

The phone system ready for the integration, as described in the documentation for the phone system.

Cisco Unity Server

Cisco Unity installed and ready for the integration, as described in the applicable Cisco Unity installation guide at http://www.cisco.com/en/US/products/sw/voicesw/ps2237/prod_installation_guides_list.html.

A license that enables the applicable number of voice messaging ports.

Integration Description

The Ericsson MD-110 PIMG integration sends call information and MWI requests through the data link, which is an RS-232 serial cable that connects the phone system and the master PIMG unit. Voice connections are sent through the analog lines between the phone system and the PIMG units. The PIMG units communicate with the Cisco Unity server through the LAN or WAN by using Session Initiation Protocol (SIP). Figure 1 shows the required connections.

Figure 1 Connections Between the Phone System and Cisco Unity

Call Information

The phone system sends the following information through the data link:

The extension of the called party

The extension of the calling party (for internal calls) or the phone number of the calling party (if it is an external call and the system uses caller ID)

The reason for the forward (the extension is busy, does not answer, or is set to forward all calls)

Cisco Unity uses this information to answer the call appropriately. For example, a call forwarded to Cisco Unity is answered with the personal greeting of the subscriber. If the phone system routes the call to Cisco Unity without this information, Cisco Unity answers with the opening greeting.


Note The Ericsson MD-110 phone system also sends requests to turn on and turn off MWIs through the data link.


Integration Functionality

The Ericsson MD-110 integration with Cisco Unity provides the following integration features:

Call forward to personal greeting

Call forward to busy greeting

Caller ID

Easy message access (a subscriber can retrieve messages without entering an ID because Cisco Unity identifies the subscriber based on the extension from which the call originated; a password may be required)

Identified subscriber messaging (Cisco Unity identifies the subscriber who leaves a message during a forwarded internal call, based on the extension from which the call originated)

Message waiting indication (MWI)

Integrations with Multiple Phone Systems

Depending on the version, Cisco Unity can be integrated with two or more phone systems:

Cisco Unity 4.0 and 4.1 can be integrated with a maximum of two phone systems at one time. For information on and instructions for integrating Cisco Unity with two phone systems, refer to the Dual Phone System Integration Guide at http://www.cisco.com/en/US/products/sw/voicesw/ps2237/prod_configuration_guide09186a0080211b2e.html.

Cisco Unity 4.2 and later can be integrated with two or more phone systems at one time. For information on the maximum supported combinations and instructions for integrating Cisco Unity with multiple phone systems, refer to the Multiple Phone System Integration Guide at http://www.cisco.com/en/US/products/sw/voicesw/ps2237/prod_configuration_guide09186a00806192a3.html.

Planning How the Voice Messaging Ports Will Be Used by Cisco Unity

Before programming the phone system, you need to plan how the voice messaging ports will be used by Cisco Unity. The following considerations will affect the programming for the phone system (for example, setting up the hunt group or call forwarding for the voice messaging ports):

The number of voice messaging ports installed.

The number of voice messaging ports that will answer calls.

The number of voice messaging ports that will only dial out, for example, to send message notification, to set message waiting indicators (MWIs), to make AMIS deliveries, and to make telephone record and playback (TRAP) connections.

The following table describes the voice messaging port settings in Cisco Unity that can be set in UTIM, and that are displayed as read-only text on the System > Ports page of the Cisco Unity Administrator.

Table 1 Settings for the Voice Messaging Ports 

Field
Considerations

Extension

Enter the extension for the port as assigned on the phone system.

Enabled

Check this check box to enable the port. The port is enabled during normal operation.

Uncheck this check box to disable the port. When the port is disabled, calls to the port get a ringing tone but are not answered. Typically, the port is disabled only by the installer during testing.

Answer Calls

Check this check box to designate the port for answering calls. These calls can be incoming calls from unidentified callers or from subscribers.

Message Notification

Check this check box to designate the port for notifying subscribers of messages. Assign Message Notification to the least busy ports.

Dialout MWI

(not used by serial or SMDI integrations)

Check this check box to designate the port for turning MWIs on and off. Assign Dialout MWI to the least busy ports.

AMIS Delivery

(available with the AMIS licensed feature only)

Check this check box to designate the port for making outbound AMIS calls to deliver voice messages from Cisco Unity subscribers to users on another voice messaging system. Cisco Unity supports the Audio Messaging Interchange Specification (AMIS) protocol, which provides an analog mechanism for transferring voice messages between different voice messaging systems.

This setting affects outbound AMIS calls only. All ports are used for incoming AMIS calls.

Because the transmission of outgoing AMIS messages may tie up voice ports for long periods of time, you may want to adjust the schedule on the Network > AMIS > Schedule page so that outgoing AMIS calls are placed during closed hours or at times when Cisco Unity is not processing many calls.

TRAP Connection

Check this check box so that subscribers can use the phone as a recording and playback device in Cisco Unity web applications and e-mail clients. Assign TRAP Connection to the least busy ports.


The Number of Voice Messaging Ports to Install

The number of voice messaging ports to install depends on numerous factors, including:

The number of calls Cisco Unity will answer when call traffic is at its peak.

The expected length of each message that callers will record and that subscribers will listen to.

The number of subscribers.

The number of ports that will be set to dial out only.

The number of calls made for message notification.

The number of MWIs that will be activated when call traffic is at its peak.

The number of AMIS delivery calls.

The number of TRAP connections needed when call traffic is at its peak. (TRAP connections are used by Cisco Unity web applications to play back and record over the phone.)

The number of calls that will use the automated attendant and call handlers when call traffic is at its peak.

It is best to install only the number of voice messaging ports that are needed so that system resources are not allocated to unused ports.

The Number of Voice Messaging Ports That Will Answer Calls

The calls that the voice messaging ports answer can be incoming calls from unidentified callers or from subscribers. Typically, the voice messaging ports that answer calls are the busiest.

You can set voice messaging ports to both answer calls and to dial out (for example, to send message notifications). However, when the voice messaging ports perform more than one function and are very active (for example, answering many calls), the other functions may be delayed until the voice messaging port is free (for example, message notifications cannot be sent until there are fewer calls to answer). For best performance, dedicate certain voice messaging ports for only answering incoming calls, and dedicate other ports for only dialing out. Separating these port functions eliminates the possibility of a collision, in which an incoming call arrives on a port at the same time that Cisco Unity takes the port off-hook to dial out.

The Number of Voice Messaging Ports That Will Only Dial Out, and Not Answer Calls

Ports that will only dial out and will not answer calls can do one or more of the following:

Notify subscribers by phone, pager, or e-mail of messages that have arrived.

Turn MWIs on and off for subscriber extensions.

Make outbound AMIS calls to deliver voice messages from Cisco Unity subscribers to users on another voice messaging system. (This action is available only with the AMIS licensed feature.)

Make a TRAP connection so that subscribers can use the phone as a recording and playback device in Cisco Unity web applications.

Typically, these voice messaging ports are the least busy ports.


Caution In programming the phone system, do not send calls to voice messaging ports in Cisco Unity that cannot answer calls (voice messaging ports that are not set to Answer Calls). For example, if a voice messaging port is set only to Dialout MWI, do not send calls to it.

Preparing for Programming the Phone System

Record your decisions about the voice messaging ports to guide you in programming the phone system.

Caution In programming the phone system, do not send calls to voice messaging ports in Cisco Unity that cannot answer calls (voice messaging ports that are not set to Answer Calls). For example, if a voice messaging port is set only to Message Notification, do not send calls to it.

Table 18 Settings for the Voice Messaging Ports 

Field
Considerations

Extension

Enter the extension for the port as assigned on the phone system.

Enabled

Check this check box to enable the port. The port is enabled during normal operation.

Uncheck this check box to disable the port. When the port is disabled, calls to the port get a ringing tone but are not answered. Typically, the port is disabled only by the installer during testing.

Answer Calls

Check this check box to designate the port for answering calls. These calls can be incoming calls from unidentified callers or from subscribers.

Message Notification

Check this check box to designate the port for notifying subscribers of messages. Assign Message Notification to the least busy ports.

Dialout MWI

(not used by serial or SMDI integrations)

Check this check box to designate the port for turning MWIs on and off. Assign Dialout MWI to the least busy ports.

AMIS Delivery

(available with the AMIS licensed feature only)

Check this check box to designate the port for making outbound AMIS calls to deliver voice messages from Cisco Unity subscribers to users on another voice messaging system. Cisco Unity supports the Audio Messaging Interchange Specification (AMIS) protocol, which provides an analog mechanism for transferring voice messages between different voice messaging systems.

This setting affects outbound AMIS calls only. All ports are used for incoming AMIS calls.

Because the transmission of outgoing AMIS messages may tie up voice ports for long periods of time, you may want to adjust the schedule on the Network > AMIS > Schedule page so that outgoing AMIS calls are placed during closed hours or at times when Cisco Unity is not processing many calls.

TRAP Connection

Check this check box so that subscribers can use the phone as a recording and playback device in Cisco Unity web applications and e-mail clients. Assign TRAP Connection to the least busy ports.

Step 3 When you hear the opening greeting, enter the extension for Phone 1. Hearing the opening greeting means that the port is configured correctly.

Step 4 Confirm that Phone 1 rings and that you hear a ringback tone on Phone 2. Hearing a ringback tone means that Cisco Unity correctly released the call and transferred it to Phone 1.

Step 5 Leaving Phone 1 unanswered, confirm that the state of the port handling the call changes to "Idle." This state means that release transfer is successful.

Step 6 Confirm that, after the number of rings that the phone system is set to wait, the call is forwarded to Cisco Unity and that you hear the greeting for the test subscriber. Hearing the greeting means that the phone system forwarded the unanswered call and the call-forward information to Cisco Unity, which correctly interpreted the information.

Step 7 On the Status Monitor, note which port handles this call.

Step 8 Leave a message for the test subscriber and hang up Phone 2.

Step 9 On the Status Monitor, confirm that the state of the port handling the call changes to "Idle." This state means that the port was successfully released when the call ended.

Step 10 Confirm that the MWI on Phone 1 is activated. The activated MWI means that the phone system and Cisco Unity are successfully integrated for turning on MWIs.


To Test Listening to Messages


Step 1 From Phone 1, enter the internal pilot number for Cisco Unity.

Step 2 When asked for your password, enter the default password. Hearing the request for your password means that the phone system sent the necessary call information to Cisco Unity, which correctly interpreted the information.

Step 3 Confirm that you hear the recorded voice name for the test subscriber (if you did not record a voice name for the test subscriber, you will hear the extension number for Phone 1). Hearing the voice name means that Cisco Unity correctly identified the subscriber by the extension.

Step 4 When asked whether you want to listen to your message, press 1.

Step 5 After listening to the message, press 3 to delete the message.

Step 6 Confirm that the MWI on Phone 1 is deactivated. The deactivated MWI means that the phone system and Cisco Unity are successfully integrated for turning off MWIs.

Step 7 Hang up Phone 1.

Step 8 On the Status Monitor, confirm that the state of the port handling the call changes to "Idle." This state means that the port was successfully released when the call ended.


To Set Up Supervised Transfer on Cisco Unity


Step 1 In the Cisco Unity Administrator, go to the Subscribers > Subscribers > Call Transfer page.

If the name of the test subscriber is not displayed, click the Find icon (the magnifying glass) in the title bar, then click Find, and select the name of the test subscriber in the list that appears.

For more information on transfer settings, refer to the "Subscriber Template Call Transfer Settings" section in the Cisco Unity Administrator Help.

Step 2 Under Transfer Type, click Supervise Transfer.

Step 3 Set the Rings to Wait For field to 3.

Step 4 Click the Save icon.


To Test Supervised Transfer


Step 1 From Phone 2, enter the access code necessary to get an outside line, then enter the number outside callers use to dial directly to Cisco Unity.

Step 2 On the Status Monitor, note which port handles this call.

Step 3 When you hear the opening greeting, enter the extension for Phone 1. Hearing the opening greeting means that the port is configured correctly.

Step 4 Confirm that Phone 1 rings and that you do not hear a ringback tone on Phone 2. Instead, you should hear the indication your phone system uses to mean that the call is on hold (for example, music or beeps).

Step 5 Leaving Phone 1 unanswered, confirm that the state of the port handling the call remains "Busy." This state and hearing an indication that you are on hold mean that Cisco Unity is supervising the transfer.

Step 6 Confirm that, after three rings, you hear the greeting for the test subscriber. Hearing the greeting means that Cisco Unity successfully recalled the supervised-transfer call.

Step 7 During the greeting, hang up Phone 2.

Step 8 On the Status Monitor, confirm that the state of the port handling the call changes to "Idle." This state means that the port was successfully released when the call ended.


To Delete the Test Subscriber


Step 1 In the Cisco Unity Administrator, go to the Subscribers > Subscribers > Profile page.

If the name of the test subscriber is not displayed, click the Find icon (the magnifying glass) in the title bar, then click Find, and select the name of the test subscriber in the list that appears.

Step 2 In the title bar, click the Delete Subscriber icon (the X).

Step 3 Click Delete.


Integrating a Secondary Server for Cisco Unity Failover

For Cisco Unity 4.1 and later, the Cisco Unity failover feature enables a secondary server to provide voice messaging services when the primary server becomes inactive. For information on installing a secondary server for failover, refer to the applicable Cisco Unity installation guide, available at http://www.cisco.com/en/US/products/sw/voicesw/ps2237/prod_installation_guides_list.html.

The Cisco Unity failover feature is not available when this phone system is integrated with Cisco Unity 4.0 through PIMG units.

For information on failover, refer to the Cisco Unity Failover Configuration and Administration Guide. The Domino version of the guide is available at http://www.cisco.com/en/US/products/sw/voicesw/ps2237/products_feature_guide_book09186a00803f70f3.html. The Exchange version of the guide is available at http://www.cisco.com/en/US/products/sw/voicesw/ps2237/products_feature_guide_book09186a00801b9241.html.

Requirements

The following components are required to integrate a secondary server:

One secondary server for each primary server installed and ready for the integration, as described in the applicable Cisco Unity installation guide and earlier in this integration guide.

A license that enables failover.

Integration Description

The Ericsson MD-110 phone system sends call information and MWI requests through the data link, which consists of an RS-232 serial cable between the phone system and the master PIMG unit. Voice connections are sent through the analog lines between the phone system and the PIMG units. The PIMG units communicate with the primary and secondary servers through the LAN or WAN by using Session Initiation Protocol (SIP). Figure 2 shows the required connections.

Figure 2 Connections Between the Phone System and the Cisco Unity Servers

The primary and secondary servers act in the following manner:

When the primary server is operating normally, the secondary server is inactive.

When the primary server becomes inactive, the secondary server becomes active.

When the primary server becomes active again, the secondary server becomes inactive.

Setting Up the Secondary Server for Failover

Do the following procedure to integrate the secondary server.

To Set Up the Secondary Server for Failover


Step 1 Install a secondary server with the same configuration as the primary server. For installation instructions, refer to the applicable Cisco Unity installation guide.

Step 5 At the prompt to restart the Cisco Unity services, click Yes.


Note When restarting the Cisco Unity services, use the UTIM prompt instead of the Cisco Unity icon in the Windows taskbar. The taskbar icon does not restart all of the Cisco Unity services.


Step 6 After Cisco Unity restarts, on the Windows Start menu of the Cisco Unity server, click Programs > Cisco Unity > Manage Integrations. UTIM appears.

Step 7 In the left pane of the UTIM window, click the phone system integration that you created in Step 3.

Step 8 For Cisco Unity 4.0 and 4.1, continue to Step 9.

For Cisco Unity 4.2 and later, do the following substeps.

a. In the right pane, click Properties.

b. On the Integration tab, compare the setting of the Integration ID field for the secondary server to the setting of the Integration ID field for the primary server.

c. If the integration IDs of the phone system on the primary and secondary server are the same, continue to Step 9.

If the integration IDs of the phone system on the primary and secondary servers are different, on the secondary server, click Modify Integration ID.

d. When cautioned that subscribers associated with the current Integration ID setting will not be automatically associated with the new Integration ID setting, click OK.

e. In the Modify Integration ID dialog box, in the Enter New Integration ID field, enter the Integration ID setting for the phone system on the primary server and click OK.

f. Click Save.

g. At the prompt to restart the Cisco Unity services, click Yes.

h. In the left pane, click the phone system integration that you created in Step 3.

Step 9 In the right pane, click the Ports tab.

Step 10 Enter the port settings to match the port settings on the primary server.


Caution In programming the phone system, do not send calls to voice messaging ports in Cisco Unity that cannot answer calls (voice messaging ports that are not set to Answer Calls). For example, if a voice messaging port is set only to Message Notification, do not send calls to it.

Step 11 Click Save.

Step 12 Repeat Step 9 through Step 11 for each remaining PIMG unit in the phone system integration.

Step 13 Exit UTIM.



Appendix: PIMG Integrations Over a WAN That Use the G.729a Codec May Need to Disable Comfort Noise



Note This appendix applies only to systems that use PIMG units with PIMG firmware release 4, SU6 or earlier.


When the PIMG units connect to a WAN, use the G.729a codec, and have firmware release 4 SU6 or earlier, you must disable comfort noise. Otherwise, callers will hear loud comfort noise after pressing a DTMF key or between prompts when recording a message.

To Disable Comfort Noise


Step 1 On the Cisco Unity server, on the Start menu, click Run.

Step 2 In the Run dialog box, enter regedit and click OK.


Caution Changing the wrong registry key or entering an incorrect value can cause the server to malfunction. Before you edit the registry, confirm that you know how to restore it if a problem occurs. (Refer to the "Restoring" topics in Registry Editor Help.) Note that for a Cisco Unity failover system, registry changes on one Cisco Unity server must be made manually on the other Cisco Unity server, because registry changes are not replicated. If you have any questions about changing registry key settings, contact Cisco TAC.

Step 3 If you do not have a current backup of the registry, save the registry settings to a file by doing the following depending on the Windows version:

Windows 2003

Click File > Export.

Windows 2000

Click Registry > Export Registry File.


Step 4 Expand the registry key
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Avaudio\Parameters
and double-click the ComfortNoise value in the right pane.
