Avaya Definity Gx/PBXLink Integration Guide for Cisco Unity 3.1
Planning How the Voice Messaging Ports Will Be Used by Cisco Unity
Integration Features
The Avaya Definity/PBXLink integration with Cisco Unity provides the following features.
Call forward to personal greeting | When an incoming call is routed to an unanswered extension, the |
| call is forwarded to the voice mail of the subscriber. The caller then |
| hears the personal greeting of the subscriber and can leave a |
| message. |
|
|
Call forward to busy greeting | When an incoming call is routed to a busy extension, the call is |
| forwarded to the voice mail of the subscriber. The caller then hears |
| the busy greeting (if the subscriber enabled it) and can leave a |
| message. |
|
|
Caller ID | Cisco Unity receives caller ID information from the phone system |
| (if available). This information appears in the subject line of the |
| message in the desktop messaging application. |
|
|
Easy message access | A subscriber can retrieve messages without entering an ID. |
| Cisco Unity identifies a subscriber based on the extension from |
| which the call originated. A password may be required. |
|
|
Identified subscriber messaging | Cisco Unity automatically identifies a subscriber who leaves a |
| message during a forwarded internal call, based on the extension |
| from which the call originated. |
|
|
Message waiting indication | When a message is waiting for a subscriber, Cisco Unity notifies the |
| phone system to activate the message waiting indicator (MWI) on |
| the subscriber extension. |

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 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.
