Abstract: Methods, systems, and computer program products for transaction-based IP telephony call processing are disclosed. According to one method, a signaling message associated with an IP telephony event is received at an IP telephony node. In response to receiving the signaling message, an IP telephony transaction instance is instantiated to process the signaling message. The signaling message is processed using the IP telephony transaction instance.

Abstract: Systems, methods, and computer program products communicating the state of a wireless user device in a wireless domain to an application server in an internet protocol (IP) domain are disclosed. According to one aspect, a system for communicating the state of a wireless user device in a wireless domain to an application server in an Internet protocol domain includes a wireless user device configured to operate in a wireless domain and configured to detect a change of its state, and, in response to detecting the change of state, to send a message service message, the message service message containing status information indicating a current state of the wireless user device. The system also includes an application server configured to operate in the IP domain and for receiving the status information indicating a state of the wireless user device and for providing at least one service to the wireless user device based on the current state of the wireless user device.

Abstract: Methods, systems, and computer program products for flexible call jumping are disclosed. According to one method, an indication is received from a calling phone for initiating a call with a called phone. The call is established between the called and calling phone. During the call, an indication is received from the calling phone to jump the call to a user selected destination. In response to receiving the indication to jump the call, the call is jumped to the destination such that the call continues between the destination and the called phone.
