METHOD AND APPARATUS FOR PROVIDING INTERNET PROTOCOL CALL TRANSFER IN COMMUNICATION NETWORKS

摘要

A method and apparatus for enabling a network provider, in concert with IP technology and protocols, to provide the ability to offer a simple pre- answer or post-answer call redirection, such as call transfer, to customers with IP endpoints is disclosed. The present invention allows call transfers to be initiated from an IP endpoint but processed in the packet network, e.g., the VolP network instead of being processed by the endpoint. When a redirecting party (RP) receives a call from a calling party (CP), the RP simply sends a VolP signaling message to the network to initiate a call transfer to redirect the call from the CP to a TP instead and the network will complete the call transfer on behalf of the RP.
