Survivable Remote Site Telephony overview
If communication between the conference station 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 conference station are available. The following table describes typical
features and feature availability. For more information about feature availability during failover, contact your
system administrator.
