New Software Features in Cisco IOS Release 12.2(2)XB
The following new software feature is supported by in Cisco IOS Release 12.2(2)XB:
Survivable Remote Site Telephony
Platforms: Cisco 7200 series routers.
The Survivable Remote Site (SRS) Telephony feature, under the IP Telephony services umbrella,
provides the Cisco CallManager with fallback support for the Cisco IP phones attached to the Cisco
router on your local Ethernet. The SRS Telephony feature enables the routers to provide call handling
support for the Cisco IP phones when the Cisco IP phones lose connection to the remote primary,
secondary, or tertiary Cisco CallManager or when the WAN connection is down.

router on your local Ethernet. The SRS Telephony feature enables the routers to provide call handling
support for the Cisco IP phones when the Cisco IP phones lose connection to the remote primary,
secondary, or tertiary Cisco CallManager or when the WAN connection is down.
Cisco CallManager 3.0 supports Cisco IP phones at remote sites attached to Cisco branch office
multiservice routers across the WAN. Prior to the SRS Telephony feature, when the WAN connection
between the remote branch office router and the Cisco CallManager failed or connectivity with the Cisco
CallManager was lost for some reason, the Cisco IP phones at the branch office became unusable for the
duration of the failure. The SRS Telephony feature overcomes this problem and enables the basic
features of the Cisco IP phones by providing call-handling support on the branch office router for its
attached Cisco IP phones. The system automatically detects the failure and uses the Simple Network
Auto Provisioning (SNAP) technology to autoconfigure the branch office router to provide call
processing for the local Cisco IP phones. When the WAN link or connection to the primary Cisco
CallManager is restored, call-handling capabilities for the Cisco IP phones switch back to the primary
Cisco CallManager. During a failure when SRS Telephony feature is enabled, the Cisco IP phone
displays a message to inform you that the Cisco IP phones are in the Cisco CallManager fallback mode
and are able to perform limited functions.
