Methods, systems, and computer program products for hairpin condition elimination in a telecommunications network are disclosed. A method is disclosed herein for eliminating a hairpin condition at a network node. According to one method, a first and second call leg, each using packet processing resources in a bearer node, are identified; if the first and second call legs are in a hairpin condition, the first and second call legs are connected together in the bearer node in a manner that bypasses and releases packet processing resources.

Methods, systems, and computer program products for synchronizing a subscriber profile in a plurality of domains is described. In one embodiment, the method includes receiving a profile update request message from an application server to modify an Internet protocol (IP) domain subscriber profile. The profile update request message is forwarded to a home location register (HLR). A cellular domain subscriber profile is modified in accordance with the profile update request message. Similarly, an updated subscriber profile data is received from the HLR. The updated subscriber profile data is converted in the IP domain. The converted updated subscriber profile data is sent to the application server.

Disclosed are methods, systems, and computer program products for notifying a Session Initiation Protocol (SIP) entity of a fast switchover event. According to one method a first SIP entity having an active host and a standby host is provided. At the active host a SUBSCRIBE message is received from a second SIP entity for subscribing to a fast switchover notification service. The standby host is switched to an active mode. In response to switching the standby host to active mode, a NOTIFY message is sent to the second SIP entity for notifying the second SIP entity that the standby host is operating in active mode.
