It works, I am doing MPLS VPN's using 3662's and running VoIP toll bypass. Customer is very pleased with the network.

VoIP over satellite? I am very sceptical about it. Better, forget such idea.
You may want to look at using H.323 gatekeepers with CAC (Call Admission Control).
Here is a link to a Whitepaper on this Subject.

I am looking for advice on technique or products that can solve the following challenge ...
Two private line T1's between A and B - one terrestial T1 with >200 ms
RTT,
the other T1 is over satellite with ~500 ms RTT. The circuits are
used
for mixed VoIP (70%) and data (30%) applications. To achieve optimal voice quality, we want to route all VoIP calls over the terrestial T1 until it is "full", then divert all subsequent VoIP calls over the satellite T1 (** while existing VoIP calls continue to be routed over the terrestial T1).
So it looks like I need per-flow (based on protocol, src IP, dst IP, src port, dst port) routing. It looks like MPLS Traffic Engineering can do
being the
job. Is there anything else that can it with less complexity?
Ideas or recommendations?
