[cisco-voip] Remote Callmanager on SAT link

[Wes Sisk]

A Cisco 1760V router with vwic-1mft-t1 should do nicely.

One thing i forgot to mention - doing h323 over any high latency link 
there is good chance for delayed audio cut through.  You're looking at 
about 10 TCP packets in each direction (give or take for fragementation, 
fast start, etc).  So you will see audio cut through delayed by 
~10*(latency).  This is a simple rough estimate.
