Um, do you mean that you need to move 1248 _simultaneous calls_ across 21 T1 circuits? There's no problem there, just pick any reasonable codec. All you need is one that uses less than 26kbps of bandwidth, and nearly all of them meet that criterion. Take a look at G.729a. It's widely used, gives reasonably good quality, and only takes half that much bandwidth. -Bill
