Centralized Voice Messaging

Cisco 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. Connection will support 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 9.x at

Integration Description

The Cisco Unified Communications Manager (CM) Express SIP trunk integration uses a LAN to connect

Cisco Unity Connection and the phone system. The Cisco Unified Communications Manager Express

router also provides connections to the PSTN. Figure 1 shows the connections.
