Question
What are two valid features of Cisco Unified Survivable Remote Site Telephony? (Choose two.)
A. Allows users to make calls with the same dial-plan as if connected to Cisco UCM cluster.
B. To get SIP trunk failover capability for Cisco UCM.
C. Using a Cisco router, it provides failover between these routers to ensure remote site operations.
D. On a router registers all phones to that remote site router if link to the central Cisco UCM cluster is lost.
E. Enables failover between two or more Cisco UCM servers in a cluster if one server is placed at a remote site.
Answer
A. Allows users to make calls with the same dial-plan as if connected to Cisco UCM cluster.
D. On a router registers all phones to that remote site router if link to the central Cisco UCM cluster is lost.
Explanation
Cisco Unified Survivable Remote Site Telephony (SRST) is a powerful solution that ensures the continuity of telephony services at remote sites, even when the connection to the central Cisco Unified Communications Manager (UCM) cluster is disrupted. The two valid features of Cisco Unified SRST are:
Allows users to make calls with the same dial-plan as if connected to Cisco UCM cluster: This feature ensures that users at the remote site can continue to make and receive calls using the same familiar dial-plan they use when connected to the central Cisco UCM cluster. By maintaining a consistent dial-plan, SRST minimizes confusion and enables seamless communication, even during network outages.
On a router registers all phones to that remote site router if link to the central Cisco UCM cluster is lost: In the event of a lost connection to the central Cisco UCM cluster, SRST automatically registers all phones at the remote site to the local SRST router. This failover mechanism ensures that telephony services remain operational, allowing users to continue making and receiving calls without interruption.
By leveraging these two features, Cisco Unified SRST provides a robust and reliable solution for maintaining telephony services at remote sites. It ensures that users can communicate effectively using the same dial-plan they are accustomed to, while also providing automatic failover capabilities to keep phones registered and operational during network disruptions.
