How an Integration Works

Lines and Cables to Make Physical Connections

Depending on the type of integration, different combinations of lines and cables are used to connect the phone system and Cisco Unity.

Integration with Cisco Unified Communications Manager

Cisco Unified Communications Manager (CM) (formerly known as Cisco Unified CallManager) and SIP proxy servers use network connections that carry all communication to and from Cisco Unity. Figure 6-1shows the network connections used in an integration with Cisco Unified CM.

Digital Integration with Digital PIMG Units

The phone system sends call information, MWI requests, and voice connections through the digital lines, which connect the phone system to the PIMG units. The PIMG units communicate with the Cisco Unity server through the LAN or WAN by using Session Initiation Protocol (SIP). Figure 6-2shows the connections used in a digital integration by using digital PIMG units.
