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.
