How to access POTS line (Line 2) with Obi212?
webraider:
Thank you for your help drgeoff! I would not have thought about the power adapter!!!

Clearly something is not quite right. An incomplete list of possibilities includes:
1. The PBX
2. The wiring from the PBX being "leaky" to somewhere or picking up interference. Is xDSL service in the building?
3. The OBi212
4. Very "dirty" 110 volt AC supply in your room or the whole building.
5. RF borme interference from outside your room or from some of your other equipment
We have not been able to conclusively eliminate any of them.
That the fault can be affected by connecting the 110 or variations in power supply arrangement do make me wonder about "stray" signals.
Is the PBX line wired to more than one wall jack? Is it possible to move the OBi212 to a different point in your apartment?
There is another test you should run to eliminate the cordless phone. Unplug the base from the Obi212 and from the mains supply. Take the batteries out of the handset. Repeat the test where the Call History showed 'Call ended' occuring at the same time as the onset of ringing.

I only have on jack so moving it isn't really an option.
I have quite a few things plugged into a power strip. This is due to me having such a small NYC apartment. It. could d in theory be any of the items plugged in, BUT I have changed to another outlet to test it there. Same issue. If I use the old plug, and plug it in correctly (ie.. the correct polarity), then it works correctly. If not, then it has the same symptoms.
What I may do is order another OBI 212 and test it to see if it does/behaves the same thing, but now that I have it working, I may just leave things the way they are.
As for the PBX, whatever it's issue may be, I'm sure it didn't just begin having that issue when I plugged in the 212. I don' know any specifics about it. It may be slightly under powered, and somehow the Ethernet port/Other plug might be adding just enough to compensate.
Just being speculative here, but if there is something slightly wrong with the OBI, do you think it could cause further issues?

If anyone is looking to make the POTS line the default outgoing line, all I had to do is enter Obi Expert Mode and set Physical Interfaces > Phone 1 > PrimaryLine to PSTN Line. With this setting:
Incoming calls on POTS or any SPs can be directly answered without any modifiers (like ##)Default dial out line is POTS. No modifiers required.To use SP1 (in my case Google Voice) as the outgoing line use **1 followed by number

Setting the Primary Line has NO EFFECT WHATSOEVER on incoming calls to the LINE jack or any SP. The Primary Line affects only the routeing of outgoing calls.
