Abstract:
A system that incorporates teachings of the present disclosure may include, for example, a Unified Messaging System (UMS) having a Session Border Controller (SBC) to receive a Session Initiation Protocol Uniform Resource Identifier (SIP URI), detect from a host portion of the SIP URI that the SIP URI is associated with a failover communication session, update a user portion of the SIP URI to indicate a failure disposition, and route the updated SIP URI to a call agent of the UMS. Additional embodiments are disclosed.
