Planning the Port Setup
Before programming the phone system, you need to plan how the voice messaging ports are used by Cisco Unity Connection. The following considerations 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.
For a Unity Connection cluster, each Unity Connection server must have enough ports to handle all voice messaging traffic in case the other server stops functioning.
-
The number of voice messaging ports that answer calls.
-
The number of voice messaging ports that only dial out, for example, to send message notification, to set message waiting indicators (MWIs), and to make telephone record and playback (TRAP) connections.
The following table describes the voice messaging port settings in Unity Connection that can be set on Telephony Integrations > Port of Cisco Unity Connection Administration.

Server |
(When a Unity Connection cluster is configured) Select the name of the Unity Connection server that you want to handle this port. Assign an equal number of answering and dial-out voice messaging ports to the Unity Connection servers so that they equally share the voice messaging traffic. |
Answer Calls |
Check this check box. All voice messaging ports connecting to the Cisco Unified CM server must have the Answer Calls check box checked. Otherwise, calls to Unity Connection may not be answered. |
Perform Message Notification |
Check this check box to designate the port for notifying subscribers of messages. |
Send MWI Requests |
Check this check box to designate the port for turning MWIs on and off. |
Allow TRAP Connections |
Check this check box so that users can use the phone as a recording and playback device in Unity Connection web applications. |
