g729 Has pretty "Decent" voice Quality. Each Call is 8k Compressed. G728
is 16k Compressed. Now, these values do not take into account IP Header
overhead.
VoIP Equipment for 51 DS1's is not going to be cheap. The best bet on the
Cisco Side is the 6500 or even a router like the 7200 the with the Voice
Card's.
Again, not cheap, but it does work pretty well..

Voice Compression
I am looking for an economical solution to compress
1248 voice DS-0s to 240 DS0s. My application is to
extend the voice and data for a call center that needs
roughly 63 T-1 equivalents of bandwidth down 21
physical T-1 ciscuits.
