Survivable Remote Site Telephony Overview
If communication between the conference station 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, 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.
When the conference station loses connectivity, it may display a message similar to this: SRST. Some
features unavailable.
