Abstract:
1. A system for enabling real-time transport protocol (RTP) multiplexing in a media gateway, the system comprising: a media gateway controller configured to receive a signaling message to establish a call from a peer node in a first network and to determine, if possible, an interface type used by the peer node to communicate a media portion of the call and to transmit a call control message that includes the interface type to a media gateway; and the media gateway comprising an Internet protocol (IP) realm database and configured to perform a first and second RTP multiplexing enablement process on the media portion of the call where determining the interface type is not possible; wherein the first RTP multiplexing enablement process includes sending a real-time transport control protocol (RTCP) Application packet to the peer node, refraining from performing RTP multiplexing on packets sent to the peer node until a reply RTCP Application packet is received from the peer node, and receiving RTP multiplexed packets from the peer node; and wherein the second RTP multiplexing enablement process includes obtaining an IP realm identifier that identifies the first network, accessing the IP realm database using the IP realm identifier to determine a predefined multiplexing enablement action for packets destined for the first network, and executing the determined predefined multiplexing enablement action on packets sent to the peer node in the first network.
