Abstract
A method of initiating a call between users with reduced call set-up times using one or more telecommunication networks. The method is provided between at least a pair of H.324-like terminals coupled to the one or more telecommunication networks. The method includes providing one or more preferences for a call associated with a first terminal and a second terminal. The one or more preferences are associated with an initial mode of operation for the call between the first terminal and the second terminal. The method also includes processing the one or more preferences as a Custom Message, embedding the Custom Message in a predetermined field of a call initiation message, and transferring the Custom Message from the first terminal to the second terminal through a telecommunication network using call signaling. The method further includes processing the Custom Message by the second terminal, transferring a Custom Response Message by the second terminal using a call signaling response message to indicate to the first terminal the initial mode of operation, and exchanging information between the first terminal and the second terminal after the initial mode of operation has been establis…
