    Erik – I believe that for G.711, the std. BW calculation was to take 64 kbps and tack on another 8 bkps for overhead, getting us to 72 kbps. For G.729, it’s the x3 rule (8 kbps x 3) for overhead (the overhead is more than the actual useful data because of increased collisions) giving us ~ 24 kbps of required BW. But I noticed you are talking 90 kbps for G.711 so my question is what are the other 18 kbps for? Just some extra margin for overhead (e.g. UDP IP headers)?
