Survivable Remote Site Telephony Overview
If communication between your phone and the Cisco Unified Communications Server is interrupted, you
receive an alert message on your phone. If you are on an active call, the call remains established, and you
enter a failover situation. This failover is the Survivable Remote Site Telephony (SRST) feature.
While in failover, not all the features of your phone are available. The following table describes typical feature
and feature availability, although not all the features may be supported on your phone . For more information
about feature availability during failover, contact your system administrator.
