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. |

1. A method comprising:
receiving, by a device comprising a processor, a first message via a communication network, the first message regarding origination of a call from originating equipment of a first subscriber of the communication network to equipment of a second subscriber of the communication network, the first message comprising a first session descriptor protocol; obtaining, by the device, routing information regarding the equipment of the second subscriber, sending, by the device, a second message to a serving device communicatively coupled with the equipment of the second subscriber, the second message comprising the routing information and the first session descriptor protocol, wherein the device and the serving device comprise nodes on a signaling path for the call; receiving, by the device, a third message from the serving device, the third message comprising a second session descriptor protocol relating to the serving device; transmitting, by the device as a session initiation protocol proxy server, the second session descriptor protocol directly to the communication network to facilitate a bearer path between the communication network and the serving device, wherein the bearer path is distinct from the signaling path. |
