PBX behind Obi110
bebphone:
From way back I have a PBX (Panasonic) installed. Now I got an Obi110 but would like to keep the PBX to make calls between phones in the house.
Simply placing the PBX behind the Obi does not work (no calls get through in either direction). Is there a way to configure the Obi to make this work?
I realize I could simply replace the PBX with an Obi for each line and may do this in the future, but for now keeping the PBX would be nice.

Is this an analog PBX? If so can you interface the OBi110 analog Line (FXO) port to the PBX as an extension?

The PBX is analog. But I want the PBX behind, not in front of the Obi. That does not seem to work, at least when I made the connection I could not get any calls through. Without the PBX no problems.

bebphone,
Some details would be helpful. What model pbx are you working with and how did you connect the OBi to the pbx?

The PBX is an Panasonic KX-TA308 with 3 pots ports to the Telco and 8 "hyprid" phone ports that accept both analog and proprietary digital phones. I'm only using the analog ports.
I've connected telco to the obi, then the obi to one of the telco ports of the pbx. Several analog phones are connected to the pbx (I have not made any changes).
The pbx alone (i.e. directly connected to the telco, not via the obi) works fine. A phone directly connected to the obi works fine. The pbx connected to the obi connected to the telco does not work: it does not make calls or receive calls.
Should this work in principle? Or does this fundamentally not work (I've heard some of these boxes use signalling beyond just dial and ring tones - but I really have no clue).
