For detailed instructions for setting up a serial (SMDI, MCI, or MD-110) PIMG integration with Cisco Unity Connection, see the following sections in this chapter:

Task List to Create a Serial (SMDI, MCI, or MD-110) PIMG Integration

Before doing the following tasks to integrate Unity Connection with the phone system using PIMG units (media gateways), confirm that the Unity Connection server is ready for the integration after completing the server installation, following the tasks in the “Installing Cisco Unity Connection” chapter of the Install, Upgrade, and Maintenance Guide for Cisco Unity Connection, Release 10.x, available at http://www.cisco.com/c/en/us/td/docs/voice_ip_comm/connection/10x/install_upgrade/guide/10xcuciumgx/10xcuciumg010.html.

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

2. Plan how the voice messaging ports are used by Unity Connection. See the “Planning the Usage of Voice Messaging Ports in Cisco Unity Connection” chapter.

3. Program the phone system and extensions. See the “Programming Phone System for a Serial Integration” section.

4. Set up the PIMG units. See the “Setting Up Analog PIMG Units for a Serial Integration” section.

5. Create the integration. See the “Creating a New Integration with the Phone System” section.

6. Test the integration. See the “Testing the Integration” chapter.

7. If this integration is a second or subsequent integration, add the applicable new user templates for the new phone system. See the “Adding New User Templates for Multiple Integrations” chapter.

Requirements

The serial (SMDI, MCI, or MD-110) PIMG integration supports configurations of the following components:

Phone System

  • A phone system that supports the SMDI, MCI, or MD-110 serial protocols.
  • For a Centrex phone system only:

– A Centrex service SMDI package, with one SMDI 4-wire private data link connected to the external modem.

– A type 202T or 212A external modem, set to 1200 baud.

  • One or more of the applicable PIMG units. For details, see the “Introduction” chapter.
  • The serial data port on the phone system connected to the serial port on the master PIMG unit through an RS-232 serial cable (which is available from Cisco).

Specifications for the serial cable are in Connecting PBX-IP Media Gateway (PIMG) to the Serial Port of a PBX at http://www.dialogic.com/support/helpweb/mg/tn117.htm.

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 Unity Connection 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.

– 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 one-way network latency.

Unity Connection Server

Centralized Voice Messaging

Unity Connection supports centralized voice messaging through the phone system, which supports various inter-phone system networking protocols including proprietary protocols such as Avaya DCS, Nortel MCDN, or Siemens CorNet, and standards-based protocols such as QSIG or DPNSS. Note that centralized voice messaging is a function of the phone system and its inter-phone system networking, not voicemail. Unity Connection supports centralized voice messaging as long as the phone system and its inter-phone system networking are properly configured. For details, see the “Centralized Voice Messaging” section in the “Integrating Cisco Unity Connection with the Phone System” chapter of the Design Guide for Cisco Unity Connection, Release 10.x, available at http://www.cisco.com/c/en/us/td/docs/voice_ip_comm/connection/10x/design/guide/10xcucdgx/10xcucdg050.html.

Programming Phone System for a Serial Integration

If you use programming options other than those supplied in the following procedure, the performance of the integration may be affected.

Caution In programming the phone system, do not send calls to voice messaging ports in Unity Connection 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 Perform Message Notification, do not send calls to it.

To Program the Phone System for a Serial Integration with Unity Connection

Step 1 Program the analog lines connecting to the voice messaging ports on the PIMG units as a multiline hunt group.

Make sure that the phone system sends calls only to Unity Connection voice ports that are set to Answer Calls. Calls sent to a voice port not set to Answer Calls cannot be answered by Unity Connection and may cause other problems.

Step 2 Enable hookflash transfer capability on each analog line that connects to the voice messaging ports on the PIMG units.

Step 3 Enable caller ID (via SMDI, MCI, or MD-110) on each subscriber extension.

Step 4 For each subscriber extension, set the call forwarding options to the following:

    • Unrestricted source
    • Forward when the extension is not answered
    • Forward when the extension is busy

 

Setting Up Analog PIMG Units for a Serial Integration

Do the following procedures to set up the analog PIMG units that are connected to the phone system for a serial integration using the SMDI, MCI, or MD-110 protocol.

These procedures require that the following tasks have already been completed:

  • The phone system is connected to the PIMG units using analog lines and the applicable RS-232 serial cable.
  • The PIMG units are ready to be connected to the LAN or WAN.
  • The PIMG units are connected to a power source.

Fields that are not mentioned in the following procedures must keep their default values. For the default values of all fields, see the manufacturer documentation for the PIMG units.

Check this check box.

Number of Ports

Enter 8.

(If you want to use fewer than eight voice messaging ports, enter the number of voice messaging ports that you want to use on this PIMG unit.)

Note For a Unity Connection cluster, the Unity Connection server must have the number of voice messaging ports that are set up on the phone system for the PIMG integration so that this server can handle all voice messaging traffic for the cluster if one of the servers stops functioning. For example, if the phone system is set up with 16 voice messaging ports, this server must have 16 voice messaging ports.

Phone System

Select the name of the phone system that you entered in Step 3.

Port Group

Select the name of the port group that you added in Step 8.

Step 12 On the Search Ports page, select the display name of the first voice messaging port that you created for this phone system integration.

Note By default, the display names for the voice messaging ports are composed of the port group display name followed by incrementing numbers.

Step 13 On the Port Basics page, set the voice messaging port settings as applicable. The fields in the following table are the ones that you can change.

 

Table 12-27 Settings for the Voice Messaging Ports

Field
Considerations

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.

Extension

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

Answer Calls

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

Perform Message Notification

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

Send MWI Requests

(Serial integrations only) Uncheck this check box. Otherwise, the integration may not function correctly.

(Digital and analog integrations only) Check this check box to designate the port for turning MWIs on and off. Assign Send MWI Requests to the least busy ports.

Allow TRAP Connections

Check this check box so that users can use the port for recording and playback through the phone in Cisco Unity Connection web applications. Assign Allow TRAP Connections to the least busy ports.

Outgoing Hunt Order

Enter the priority order in which Unity Connection uses the ports when dialing out (for example, if the Perform Message Notification, Send MWI Requests, or Allow TRAP Connections check box is checked). The highest numbers are used first. However, when multiple ports have the same Outgoing Hunt Order number, Unity Connection uses the port that has been idle the longest.

Step 14 Select Save.

Step 15 Select Next.

Step 16 Repeat Step 13 through Step 15 for all remaining voice messaging ports for the phone system.

Step 17 In Cisco Unity Connection Administration, expand Telephony Integrations, then select Phone System.

Step 18 On the Search Phone Systems page, under Display Name, select the name of the phone system that you entered in Step 3.

Step 19 Repeat Step 7 through Step 18 for each remaining PIMG unit integrated with Unity Connection.

Note Each PIMG unit is connected to one port group with the applicable voice messaging ports. For example, a system that uses five PIMG units requires five port groups, one port group for each PIMG unit.

Step 20 To create a port group for MWIs, do the following substeps.

Note All MWI requests are handled by the master PIMG unit and sent to the phone system over the RS-232 serial cable (without using voice messaging ports). So the following substeps create a separate port group without voice messaging ports and enable the port group for MWIs that are “not port specific” (they do not use ports).

a. In Cisco Unity Connection Administration, expand Telephony Integrations, then select Port Group.

b. On the Search Port Groups page, select Add New.

c. On the New Port Group page, enter the applicable settings and select Save.
