I want to use this device as an outside (CO) line on my home PBX, a Panasonic KX-TDA50.
With the OBi100 connected to a CO port on the PBX, the PBX gives an error tone when I try to access the OBi100 as an outside line from an extension phone, and incoming calls on the OBi100 don't ring through. The same CO port works fine with a regular phone line plugged into it.
I can make and receive calls on the OBi100 using my Google Voice number and a regular telephone (POT).
I have updated to the latest software.
Any suggestions would be appreciated.
From what you describe, I would think that it would work.
Are you positive about the cable you are using between the OBi Phone Port and the PBX? The analog phone circuit is 2-wires. Any chance the cable is not using the 2-center pins at both ends of the cable. Is it the same cable you use to checkout the OBi with an analog phone? Can you put a splitter on the cable and hear the phone ring when the OBi is ringing the line?
The OBi should be putting out a talk voltage of about 48v. You can check the OBi adapter by logging into it from your local computer and verify that the OBi is putting out a talk voltage of about 48v and is on-hook. The PBX probably has some LEDs that show the same.
Thank you for your response, which helped to solve the problem.
While checking the voltages per your suggestion, I found the place on the switch where I should have plugged in the wire from the OBi100.
It works fine now. ;)
