System and method for assisting in controlling real-time transport protocol flow through multiple networks

The session router of claim 14, further comprising:

• a network interface configured to receive a signaling message establishing a session between an originating endpoint and a terminating endpoint;
• and
• wherein the processor is further configured to:
• search the TRIB for at least one route having a destination field matching the terminating endpoint in the received signaling message;
• compare at least one attribute of each matching TRIB route with a field in the received signaling message to determine a degree of match for the attribute;
• select, based on the comparison, one of the matching TRIB routes;
• and
• forward the signaling message to a second session router identified by a next hop attribute in the selected TRIB route.

A computer readable medium having a program for routing call signaling messages received by a first session router from a call endpoint to a second session router, the method utilizing a telephony route information base (TRIB) residing in the first session router and allowing multiple routes to the same destination, the program comprising logic for performing the steps of:

• receiving a signaling message establishing a session between an originating endpoint and a terminating endpoint;
• responsive to the received signaling message:
• searching the TRIB for at least one route having a destination field matching the terminating endpoint in the received signaling message;
• comparing at least one attribute of each matching TRIB route with a field in the received signaling message to determine a degree of match for the attribute;
• selecting, based on the comparison, one of the matching TRIB routes;
• and
• forwarding the signaling message to a second session router identified by a next hop attribute in the selected TRIB route.
