Thanks for the suggestion, Patrick. But I failed to mention that in this case, the CallManager and VoIP gateways are at site A and all the IP phones are at site B. As far as I know, the Cisco IP phones do not use H.323 gatekeeper directly. In order for the H.323 gatekeeper idea to work, I would need a CallManager at site B and run an H.323 inter-cluster trunk between the CallManagers at site A and B. Right?

Two private line T1's between A and B - one terrestial T1with >200 ms RTT,the other T1 is over satellite with ~500 ms RTT. Thecircuits are being usedfor mixed VoIP (70%) and data (30%) applications. Toachieve optimal voicequality, we want to route all VoIP calls over theterrestial T1 until it is"full", then divert all subsequent VoIP calls over thesatellite T1 (**while existing VoIP calls continue to be routed over theterrestial T1).So it looks like I need per-flow (based on protocol, srcIP, dst IP, srcport, dst port) routing. It looks like MPLS TrafficEngineering can do thejob. Is there anything else that can it with less complexity? Ideas or recommendations? Regards, Joe
