Abstract: In one aspect, a method of establishing a reduced setup time session through a gateway is provided which includes: receiving a first capability message transmitted from the first terminal to the gateway; receiving a second capability message transmitted from the second terminal to the gateway; transmitting first and second capability response messages from the terminal to the first and second terminals, respectively; receiving a media stream transmitted from the second terminal to the gateway; processing the media stream, including identifying a temporal feature in the media stream that enables a decoder to establish a decoder refresh point; receiving an acknowledgment message transmitted from the first terminal to the gateway; and, thereafter transmitting the processed media from the gateway to the first terminal.

Abstract: A method of establishing a reduced setup time session through a gateway includes receiving a first capability message transmitted from the first terminal to the gateway and receiving a second capability message transmitted from the second terminal to the gateway. The method also includes processing the first capability message and the second capability message to form a third capability message and a fourth capability message. The method further includes transmitting a third capability message from the gateway to the first terminal and transmitting a fourth capability message from the gateway to the second terminal. Moreover, the method includes receiving a first request message transmitted from the second terminal to the gateway and transmitting a second request message from the gateway to the first terminal. Transmitting the second request message is performed independent of receiving the first request message.
