Abstract
A call transfer may be prompted by a first endpoint, from the active status—open bearer channels between the first endpoint and a second endpoint—in a communications network based on ITU-T Standard H.323. The call transfer is effected by a series of steps, namely a facility message for call transfer, including an address for the third endpoint, is transmitted to a proxy function; a connection setup message is transmitted from the proxy function to the third endpoint and the third endpoint responds by transmitting a call connect message to the proxy function; the connection between the first endpoint and the second endpoint is released; and the proxy function initiates a connection to be set up between the second endpoint and the third endpoint.
