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.

Two private line T1's between A and B - one terrestial T1 with >200 msRTT,the other T1 is over satellite with ~500 ms RTT. The circuits are beingusedfor mixed VoIP (70%) and data (30%) applications. To achieve optimal
voice
quality, we want to route all VoIP calls over the terrestial T1 until itis"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
the
job. Is there anything else that can it with less complexity? Ideas or recommendations? Regards, Joe
