Methods and system for fast session establishment for H.324 and related telecommunications terminals

摘要

A method of reducing a call set-up time for a call between a pair of H.324-like terminals includes providing a first capability for the call, processing the first capability to form a first message, establishing a bearer channel, and transmitting the first message from the first terminal to the second terminal through the telecommunications network using the bearer channel. The first capability is associated with an initial mode of operation for the call. The method also includes receiving a second message transmitted from the second terminal to the first terminal. The second message includes a second capability associated with the initial mode of operation for the call. The method further includes determining that a conflict exists between the first capability and the second capability, resolving the conflict by modifying at least one of the first capability or the second capability, and transmitting information from the first terminal to the second terminal.
