Abstract
A method of improving communication in a SIP-enabled communication network which involve a variety of communication devices. By the method, a call, either entirely or just a selected medium stream of the call, may be switched, easily and seamlessly to a different channel for different media, either on the same device or on a separate device connected to the network, either during call-setup or after a call session has been established. The call may also initiate a application sharing session so that caller, callee and those participated in the call (in conference mode) may see the content of the same document or whiteboard on a screen while keeping voice communication over the phone.
