Incoming calls on pots line port not ringing through to the phone.
ianobi:
Yes the 9 followed by pause is a good point. If this goes ahead, then we need gary to provide detailed info on how his parents will dial numbers. It may be dial 9 then wait for outside dial tone, then dial ten digits. It may be 9xxxxxxxxxx in a speed dial. All sorts of possibilities.
Also, what about 911? Is that handled by the PBX or does it need to be dialled as 9911? All sorts of questions.

Sorry for my absence of late... but I had no new data to report until the latest tests which we ran late last night on my parents OBi110.
First I changed the Line Port DigitMap
from (<10>[2-9]xxxxxx|xxxxxxxS4|1xxxxxxxxxx|xx.)
to (xxxxxxxS4|1xxxxxxxxxx|xx.)
I take it this would only have affected OUTGOING calls on the line port?
Next I placed some incoming calls through the PBX line connected to the OBi's Line Port. While the line was ringing, I monitored the 'Status > Call Status' screen... refreshing the screen several times... and saw nothing, just the usual "Number of Active Calls: 0". To be sure that I was not missing this via the OBiTalk portal, I had my parents log directly into the unit, and they saw the same results.
I also had them look at the Call History (not accessible via the OBiTalk portal), and it had no record of the 3 or 4 calls I had made by that point in the evening.
So... even though the OBi's line-LED flashes during a call, and the phone & line port status indicates ringing, the unit is NOT recognizing and responding to the incoming call.
PBX ring patterns... When the call originates from outside the retirement community's PBX, it is a single long ring. When the call originates from within the retirement community, it is a double-ring. Neither ring is recognized by the OBi110.
Next we tried changing the following parameter:
Physical Interfaces > Line Port > RingValidationTime
The default value is 256, we tried 200, 150, & 640 ms... no change, still no ring.
(Note the 8/26/2012 OBi Admin Guide shows the default value as 640ms)
Now here is something really odd... I don't know if this is related or not...
My parents answering machine died - so I sent them one I had here that I'm not using (AT&T 1718)... it's a digital machine and seemed to be in fine working condition. They plugged it into their PBX line and turned it on... it answers the call, plays the greeting message, beeps, records the message (they can monitor and hear the caller leaving the message)... but upon message playback... there is nothing... no messages! If the memo button is pressed and a memo recorded, it will playback ok. But plug it into the OBi110's phone port, and it works perfectly! Verrrry strange!

Verrry strange indeed.
I would put an analog voltmeter on the PBX line during the recording to see if there was something that might have made the answer machine think that the other end hung up. I would look for even a blip on the meter. Yet if that were the case, why did the answer machine continue to pass audio? I don't know.

Yes, that's correct. Although, if we ever get this working, a much better digitmap could be constructed to suit your parents.
Have you tried all of the "low voltage" suggestions at the same time? Such as:
TipRingVoltageAdjust
RingThreshold
RingValidationTime
RingerImpedance
I have no idea what that last one might do!
Answering machine: Are you suggesting that when it is plugged into the OBi Phone Port it receives ringing and answers it? If so, then surely a phone would also ring? It does seem the answering machine is happier with a 48v "line" provided by the OBi Phone Port, rather than a low voltage line provided by the PBX.
ProfTech:
Interesting that your device has 2781M firmware. We knew Obi was shipping 2776 a while back but has never posted it. Now it looks like there are even newer releases. Makes one wonder what changes / updates there have been. The M suffix is interesting too.
