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 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.
To configure settings for the voice messaging ports in Unity Connection, navigate to Cisco Unity Connection Administration, expand Telephony Integrations and select Ports. Select an applicable port and modify the settings on Port Basics page. For more information on configuring ports, see the “Configuring Ports” section of the “Telephony Integration” chapter of the System Administration Guide for Cisco Unity Connection, Release 14, available at https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/connection/14/administration/guide/b_14cucsag.html.
