Survivable Remote Site Telephony Overview

If communication between your phone and the Cisco Unified Communications Manager 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. The Survivable Remote Site Telephony (SRST) feature handles this failover.
While in failover, all the features of your phone are not available. The following table describes typical feature
and feature availability, although not all the features may be supported on your phone. For more information,
contact your system administrator.
When your phone loses connectivity, your phone may display a message like this:
Service interruption.
