  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 TIMG Integration section.

  4. Set up the TIMG units. See the Setting Up the TIMG Units scetion.

  5. Create the integration. See the Creating an 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) TIMG integration supports configurations of the following components:

Phone System

  • A phone system that supports the SMDI, MCI, or MD-110 serial protocols.

  • T1 digital trunk interface card.

  • The firmware must be configured to support T1 line-side signaling.

  • T1 CAS connections to the TIMG units using the FXS/FSO or E&M protocol.

  • One or more TIMG units (media gateways).

  • The serial data port on the phone system connected to the serial port on the master TIMG unit with 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 T1 digital lines (DS1 or “dry T1” digital lines only) to the ports on the TIMG units.


    Caution
    T1 (or “wet T1”) connections to the PSTN must be through an MTU, CSU, or other device that provides line isolation. Otherwise, the TIMG units may be damaged.

  • The TIMG units connected to the same LAN or WAN that Unity Connection is connected to.

  • If the TIMG 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.

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

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.

Programming Phone System for a Serial TIMG 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.

Instruct the phone system technician to set up the phone system in the manner as directed in the following procedure.

Programming the Phone System for a Serial Integration with Unity Connection

Procedure

Step 1

Program the analog lines connecting to the voice messaging ports on the TIMG 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 TIMG 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 the TIMG Units

Do the following procedures to set up the analog TIMG units (media gateways) that are connected to the phone system.

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

  • The phone system is connected to the TIMG units using T1 digital lines and the applicable RS-232 serial cable.

  • The TIMG units are connected to a power source.

  • The TIMG units are ready to be connected to the LAN or WAN.


    Caution
    Because TIMG units have the same default IP address, you must set them up one at a time. Otherwise, you can experience IP address conflicts.

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 TIMG units.
