Abstract

See full text

A system that incorporates the subject disclosure may include, for example, a serving device receiving a first message from a gateway device coupled to a communication network, the first message comprising a first session descriptor protocol relating to a port of the network connecting to equipment of a first subscriber of the network to originate a call to a mobile communication device of a second subscriber of the network, whereby the serving device and the gateway device comprise nodes on a signaling path for the call. The serving device sends a second message to the gateway device, the second message comprising a second session descriptor protocol relating to the serving device, for delivery to the network to facilitate a bearer path between the network and the serving device, wherein the gateway device is not a node of the bearer path. Other embodiments are disclosed.
