Patent ID: 7298747

Claim:
A method of setting up communications in a system comprising a packet switching network, between at least one call server connected to the network, at least one media gateway connected to the network at a gateway address, a first collection of terminals connected to the network at respective terminal addresses, and a second collection of terminals connected to interfaces of the media gateway, wherein each terminal is associated with the call server in respect of signaling processing, the method comprising the following steps for setting up a communication between calling and called terminals: creating a first call processing task in the call server associated with the calling terminal; transmitting, by the first call processing task, a setup message including at least one identifier of the called terminal and a first network address making it possible to reach the calling terminal; in response to the receipt of said setup message, creating a second call processing task in the call server associated with the called terminal; sending, from the second call processing task to a second network address making it possible to reach the called terminal, of signaling information indicating at least said first network address; when the first and second network address are identical and correspond to the gateway address, setting up within the gateway having said gateway address communication path between the calling and called terminals, not passing through the packet switching network.
