Requirements

The Avaya Definity G3 in-band TIMG integration supports configurations of the following components:

Phone System

Avaya Definity G3 phone system.

T1 digital trunk interface card.

One or more TIMG units (media gateways).

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 Cisco 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 one-way network latency.

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

Cisco Unity Connection Server

Cisco Unity Connection installed and ready for the integration, as described in the applicable Cisco Unity Connection 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.

Centralized Voice Messaging

Cisco 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 voice mail. Connection will support 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 Cisco Unity Design Guide Release 7.x at http://www.cisco.com/en/US/docs/voice_ip_comm/connection/7x/design/guide/7xcucdg.html.

Programming the Phone System for an In-Band TIMG Integration with Cisco Unity Connection

Revised December 16, 2008

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 Cisco 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 Avaya Definity G3 Phone System


Step 1 Create a coverage path which contains the TIMG unit hunt group number as the coverage point.

Step 2 Assign the coverage path that you created in Step 1 to the user stations that must forward to the voice messaging ports on the TIMG units when calls are not answered or when the user station is busy, based on one of the call transfer types shown in Table 3-1.

Table 3-1 Call Transfer Types 

Transfer Type
Usage

Release transfer

(blind transfer)

Program the user station to forward calls to the pilot number when:

The extension is busy.

The call is not answered.

Supervised transfer

Program the user station to forward calls to the pilot number only when the call is not answered (on the phone system, the number of rings before forwarding must be more than the number of rings to supervise the call). Confirm that call forwarding is disabled when the extension is busy.


Step 3 Assign an extension number for each voice messaging port, which is a digital line that connects to the TIMG unit, and set the voice messaging port options as shown in Table 3-2.


Note We recommend that you distribute the voice messaging ports among multiple phone system line cards so that call processing can continue even if a line card becomes inactive.
