Cisco Unified Survivable Remote Site Telephony Configuration

---

This chapter provides an overview of how Cisco Unified Survivable Remote Site Telephony (SRST) was configured during Cisco Unified Communications Release 5.0(2) testing for IP telephony systems. Unified SRST allows an IOS gateway at a remote location to provide Cisco Unified CallManager functionality with a limited feature set and to assume control of call processing if Unified CallManager servers at the central site become unreachable.

This chapter includes the following sections:

•Cisco Unified CallManager Configuration for Unified SRST

•Unified SRST Configuration Files

Cisco Unified CallManager Configuration for Unified SRST

Unified SRST was configured in Cisco CallManager Administration as part of the device pool for phones at remote sites. First, the SRST reference for each remote site was configured. Then SRST references were associated with device pools. In this way, when a phone downloads its configuration, it receives the following information:

•Primary Unified CallManager server

•Secondary and tertiary Unified CallManager servers, if applicable

•SRST Unified CallManager server

Table 14-1 provides an example of how remote site SRST references were configured in the SRST Reference Configuration page for the following SRST gateways:

•HNL1-SRST and HNL2-SRST in sites HNL1 and HNL2 that are normally managed by a Unified CallManager cluster split across the San Jose (SJC) and Rockford (RFD) sites.

•Remote-3845 in the Dallas (DFW) site, normally managed by a Unified CallManager in the same site.

See the "North America Site Models" section for a description of each of these site models. To access the SRST Reference Configuration page, choose System > SRST from the Cisco CallManager Administration application.

Table 14-1 Unified CallManager SRST Reference Configuration

Is SRST Secure?	No (unchecked)	No (unchecked)	No (unchecked)

1 This address must be configured for Unified SRST servers supporting SIP phones. Not required for H.323 or MGCP environments.

Table 14-2 provides an example of how the SRST references shown in the previous table were associated with device pools for the remote site. This configuration was made in the Device Pool Configuration page. You access this page by choosing System > Device Pool from the Cisco CallManager Administration application.

Unified SRST Configuration Files

An Unified SRST configuration file is a standard H.323, MGCP or SIP gateway configuration file with additional commands that allow a site to continue to function without connectivity to the centralized Unified CallManager.

Unified SRST Configuration for a H.323 Gateway

This section shows a configuration file that includes the following:

•Configuration for a fully functional H.323 gateway (HNL1-SRST) when the centralized Unified CallManager is reachable

•Commands to make the router function as in a stand-alone site if connectivity to the centralized Unified CallManager is lost
