To know more about integrating Unity Connection with phone system, see the “Integrating Cisco Unity Connection with the Phone System” chapter of Design Guide for Cisco Unity Connection, Release 15, available at https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/connection/15/design/guide/b_15cucdg.html After understanding how the Unity Connection integrates with a phone system, you need to configure and edit the settings for phone system, ports, port group, trunk, and security in Unity Connection.
