Abstract

A method for communicating messages from a media gateway is disclosed. A thread pair comprising a communication protocol control stack thread and one or more media gateway adapter threads is assigned to a message from a media gateway. The thread pair is associated with a processor. The message is received from the media gateway at the communication protocol control stack thread, and is routed to a media gateway adapter thread corresponding to a communication protocol. The message is processed according to the communication protocol, and is sent to a call agent.
