I could be wrong (it's happened plenty of times), but as long as the
systems connect, then in theory you should be able to just dial the
number.

For instance, suppose Zaptel group 1 connects to the PSTN, and group 2
connects to your PBX.  You should be able to have something like:

[fromgroup1]
exten => 1024,1,Dial(Zap/g2/1024)

This would then pass through the DID to the next line.

I only have PRIs available, and only have 1 non-production server, so I
don't have a very good test bed available.  Can someone with a T1 test
this and let us know if it works as expected?
