[cisco-voip] Multi Site Environment without dedicated voice bandwidth..

[Peter Slow]

the problem here is that its a real gamble. You've seen it work, and
i've seen it degrade to the point where it was completely unusable.
The real problem you have with this sort of thing is the amount of
time/effort it takes to actaully get useful troubleshooting data if
you ever get to that point.
