Remember to add the RTP, UDP and IP overheads.
And
then just do the math.
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.

Steve,
I
want to end up with a system that will let me send and receive
voice
calls. I guess what I want to do depends on the best way
to do that.
Can I do more than 23 (decent sounding) voice calls on a
data T-1 with
someone else handling the final part of the call to the
copper for me?
If so than that is my likely final destination.
I
have a channelized voice T-1 currently plugged into my meridian
system,
but I would like (if realistically possible) to do as much of
this over
IP as possible for maximum flexibility. Is that a pipe
dream
or just silly given the current state of technology?
I am
lucky enough to work for a company that is letting me take my time
with
this, test the various options and come up with the
proper
solution. I am assuming (I know: dumb to assume) at
this point that
VoIP over a T-1 to a provider that can then route it to
hard phones for
me would be the way to go. Similarly, I would
point my 800 number to a
DiD hosted by a VoIP provider that would then
route the call back to
me. If that is an incorrect assumption,
please let me
know.
Regards,
Warren
