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

[Steve Jones]

If your T1 is currently configured for connecting you to the Internet,
then your Asterisk just becomes a client on your network, and can
terminate calls to Internet based providers by SIP or IAX.  No reason
for a T1 card or connection to the Asterisk.  I don't have enough
experience to say who may be the most reliable provider, but you can use
any of them for testing.  

Others have given details of bandwidth requirements for the different
codecs, and know more than I about that..

Once you get the basics connected, then any 800# provider should be able
to point a number to any existing DID, or you can use a VoIP provider to
provide an 800# directly.

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
