ABSTRACT:
A method and system for dynamically delivering a voice call to a client station depending on whether the client station is currently in a mode in which it can receive data. A switch may receive a request to connect a voice call to a client station that the switch serves, and a determination may responsively be made as to whether the client station is in a mode in which it can receive data communications. If the determination is that it is not in the mode, then the switch may deliver the voice call to the client station by normal routing mechanics. On the other hand, if the determination is that it is in the mode, then the switch may re-direct the call to a circuit/packet gateway that may then extend the call as a voice-over-packet session to the client station.
