Multiple Cisco Unified Communications Manager Express Routers Integrating with a Single Cisco Unity Server

Chapter 6 Integrating Cisco Unity with the Phone System

Integrating with Cisco Unified Communications Manager Express (by Using SCCP or SIP)

Multiple Cisco Unified Communications Manager Express Routers Integrating with a Single Cisco Unity Server

A single, centralized Cisco Unity server can be used by multiple Cisco Unified CM Express routers. This configuration requires that one Cisco Unified CM Express router be on the same LAN or WAN as the Cisco Unity server, and that this Cisco Unified CM Express router register all Cisco Unity voice messaging ports. The Cisco Unified CM Express router (the SIP MWI server) is a proxy server that relays SIP MWI messages between the Cisco Unity and all other Cisco Unified CM Express routers (the SIP MWI clients). Note that Cisco Unity voice messaging ports register with only the SIP MWI server (the Cisco Unified CM Express router that is on the same LAN as the Cisco Unity server), not with the SIP MWI clients.

For information on configuring Cisco Unity to support multiple Cisco Unified CM Express routers, see the applicable Cisco Unity integration guide at http://www.cisco.com/en/US/products/sw/voicesw/ps2237/products_installation_and_configuration_g uides_list.html.

Integrating Cisco Unity with Cisco Survivable Remote Site Telephony (Cisco SRST)

Cisco Unified Survivable Remote Site Telephony (SRST) can send and receive voice messages from Cisco Unity during Cisco Unified CM fallback. When the WAN is down and Cisco Unity has Basic Rate Interface (BRI) or Primary Rate Interface (PRI) access to the Cisco SRST system, Cisco Unity uses ISDN signaling (see Figure 6-10).
