Cory, it's called dialplan magic it realy depends what PBX it is, not
all of them allow dial plan magic. But it is possible on most pbxes.

CF: What exactly is "diaplan magic"?  I googled but found little info.

The basic use case in Cory's posting does not seem to require special programming in PBX, if my understanding is correct:

<phones 1,2,3 > --- (FXS' 1,2,3)<PBX>(FXS' 4,5,6) --- (A-FXO's 4,5,6)<Asterisk A>
                                    |---- { IP } ----|
                  <Asterisk B>(B-FXS' 4,5,6) --- <phones 4,5,6>

In this case, Asterisks A and B only need to agree on sending the same signals received by A-FXO 4 (which always come from PBX-FXS 4) to B-FXS 4 (onto phone 4), and sending the same numbers received by B-FXS 4 (from phone 4) to PBX-FXO4 (via A-FXO 4) and so on. PBX would have no knowledge that it's not talking to a POTS phone. Is this correct?

Has anyone had any experience using FXO and FXS gateways to extend
legacy PBX extensions to remote users?  I have a customer who needs to
do this, but wants seamless, two way communication, with a SIP server
and without the need for 2-stage dialing.  If anyone has any experience
with a solution please let me know.

Thanks
