Abstract
An enhanced circuit-switched media transmission over packet-switched, or Internet Protocol, access networks. Access legs of calls between terminal devices are monitored at a gateway positioned at the interface between packet-switched and circuit-switched networks. Access legs are identified which connect terminal devices residing in the same access network through monitoring of media data transmission. Terminal devices with identified connections are instructed to communicate directly while the gateway maintains the connection on the circuit-switched network.
