ABSTRACT:
Methods, systems, and computer program products for inhibiting message traffic to an unavailable terminating SIP server are disclosed. According to one method, at least one list of SIP servers accessible by a call session control function (CSCF) is maintained at an originating CSCF. The list includes at least one of availability and unavailability status information for the terminating SIP servers. A request is received to contact a destination via a one of the terminating SIP servers. The list is indexed and a first terminating SIP server is identified. If the first terminating SIP server is determined to be unavailable based on information in the list, a second terminating SIP server is identified using the list.
