[Asterisk-Users] How to use a data T-1?

[William Piper]

Depends on the codec. If you are using ulaw, you will only be able to have
about 23 calls. If you use g729 you can have as many as 187 simultanious
calls on a data T1.

Remember, you have 1544Kbs of bandwidth.
g279=8Kbs per call
uLaw=64Kbs per call

Just do the math.
