There are a number of ways to do this.  You can use your Dual T1 to do
what you want.  You bring your CO T1 line to the card which gives your
inbound and local outbound.  Your 2nd T1 can go to your legacy PBX.  You
just have to setup your dial plan accordingly to route the calls the way
they need to go.  I have the same situation @ my office.

Subject: [Asterisk-Users] T1 passthrough/middleman

Is it possible to act as a middle man on a T1 line?

My installation currently has an aging Inter-Tel Axxess box with a T1
coming in (16 in, 8 out). Rather than adding and replacing phones and
cards as they die, I would like to slowly migrate to a asterisk SIP
installation.

I want to take the incoming T1 line, use any available outgoing lines
for outgoing SIP, intercept any incoming lines and either send them off
to a SIP line or pass them through to other T1 line (going to the Axxess

box), and finally take in outgoing calls from the Inter-Tel box and
either send them to SIP or send them to the outside T1 line.

How will a dual T1 card be set up in this situation? Would it be easier
to use an FXO channel bank (or card) and connect analog lines to the FXS

analog lines on the Inter-Tel box?
