Integration Description

Integration Functionality

The Cisco Unified CM SIP trunk integration with Cisco Unity Connection provides the following features:

  • Call forward to personal greeting

  • Call forward to busy greeting

  • Caller ID

  • Easy message access (a user can retrieve messages without entering an ID; Cisco Unity Connection identifies a user based on the extension from which the call originated; a password may be required)

  • Identified user messaging (Cisco Unity Connection automatically identifies a user who leaves a message during a forwarded internal call, based on the extension from which the call originated)

  • Message waiting indication (MWI)

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. For details, see the “Centralized Voice Messaging” section in the “Integrating Cisco Unity Connection with the Phone System” chapter of the Design Guide for Cisco Unity Connection, Release 15 at https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/connection/15/design/guide/b_15cucdg.html.
