Cisco Survivable Remote Site Telephony Version 2.1
The Cisco Survivable Remote Site (SRS) Telephony feature provides Cisco CallManager with fallback
support for Cisco IP phones attached to a Cisco router on your local network. The SRS Telephony feature
enables routers to provide call-handling support for Cisco IP phones when they lose connection to
remote primary, secondary, or tertiary Cisco CallManager installations, or when the WAN connection is
down. Cisco CallManager version 3.2 supports Cisco IP phones at remote sites attached to Cisco
multiservice routers across the WAN. Prior to the SRS Telephony feature, when the WAN connection
between a router and Cisco CallManager failed, or when connectivity with Cisco CallManager was lost
for some reason, Cisco IP phones on the network became unusable for the duration of the failure. The
SRS Telephony feature overcomes this problem and ensures that the Cisco IP phones offer continuous
(yet minimal) service by providing call-handling support for Cisco IP phones directly from the SRS
Telephony router. The system automatically detects a failure and uses Simple Network Auto
Provisioning (SNAP) technology to autoconfigure the branch office router to provide call processing for
Cisco IP phones registered with the router. When the WAN link or connection to the primary
Cisco CallManager is restored, call-handling reverts back to the primary Cisco CallManager.
