[Asterisk-Users] Asterisk integration with office PBX

[Joe Pukepail]

Best way is to have a PRI interface to your PBX, I don't have any experience
with NEC, but with our nortel system this is what we did.  You program your
PBX to send extension 123 out the PRI, asterisk sees the call and routes it
accordingly.
