Incoming calls on pots line port not ringing through to the phone.
ianobi:
I’m surprised that the OBi does not detect ringing at the low setting that you tried. I wonder if the OBi is detecting each burst of ringing, but for some reason thinks the PSTN call is disconnecting after that burst, then sees another burst of ringing followed by disconnection etc.
Keep the ring detect settings etc low and change this:
Physical Interfaces > LINE Port > RingDelay: from 4000 to 0
If the above theory is true, that might get some sort of ringing through to the phone.
With RingDelay at “0”, next try to disable every possible method of “PSTN Disconnect Detection”. If any of this works we can add some back in later.
As the OBi works at your home, I can only think that there is something very weird about the PBX.

Do we need to give up on this and get 2-line phones, one line for the OBi and one line for the PBX?
Presuming that you cannot get changes made to the PBX, pretty much Maybe. Yet what confidence do you have that the 2-line phone will recognize the ring? However your parents may be as well off just using a separate phone for the PBX line to provides the ringing sound. The PBX line could also be connected to the OBi. What calls come in on the PBX line anyway-- just the neighbors and the doorbell?
Recapping, the main symptom is that incoming calls on the PBX are not recognized by the OBi110. Remind me. Do outgoing calls work if you dial **8 and wait for the PBX dialtone before proceeding? Can you dial **8 to pick up an incoming call from the line if you somehow knew that the call was coming in?
Taking a multimeter to your parents place could identify what is up, but it is moot if you cannot do anything about it. It could tell you why the OBI and answer machine don't work well if you are curious.

The PBX line IS their new main phone line. They notified friends, family, banks, etc of this new number when they moved to the retirement home. We decided to port their old number to GV, for several reasons... they had had the number for 40-years, and the new number is subject to regional tolls, etc.
The PBX line is also tied into wall mounted units in each room for emergency access and even one unit which notes if there is any activity in the apartment.

When dialing out through the OBi110, # will select the analog (PBX) phone line and outgoing calls can be placed. GV works fine for both incoming & outgoing calls. The problem has been that incoming calls on the analog (PBX) phone line are not passing through the OBi110 to the attached phone.
We tried a **8 during an incoming call with no success. :-(
The current workaround has been all the phones but one are connected to the PBX line, and one phone is on the OBi.

There is something indeed very wierd about the PBX!
OK, my parents & I have spent a lot of time fiddling with settings... and we've had some success!! :-))))
Give me a bit of time to review my notes and try to summarize things... it appears that 5-parameters may be involved.

OK... here is the rough sequence of events... I'm leaving lots out, only because of the many many setting we were playing with.
All of the following parameters (except 1) are on the Physical Interfaces > Line Port page.
RingDelay: 4000 --> 0
RingThreshold: 40-49 --> 19-23
The phone rang!!! When picking up the phone, one hears a dial tone, and then the phone starts to ring again when hung up!
Further reductions in RingThreshold and returning it to the default does not change this behavior.
RingDelay: 0
DetectCPC: no
DetectPolarityReversal: no
DetectFarEndLongSilence: no
DetectDisconnectTone: no
Still as before... the phone rings, hear dial tone, rings again upon hang up.
Settings as above, but changed,
TipRingVoltageAdjust: 3.5V --> 3.2V
Still as before... the phone rings, hear dial tone, rings again upon hang up.
Settings as above, but tried several additional settings for,
RingDelay: 0 --> 1000 --> 500
NO RING!!
Settings as above, but changed
RingDelay: back to 0
RingValidationTime: 256 --> 100
This one was odd, and non-repeatable. I called, the phone rang, was answered, I heard "hello" then the phone was physically dropped and hung up. We could not repeat this apparent success.
Added an additional change into the above mix,
RingIndicationDelayTime: 512 --> 256
Still as before... the phone rings, hear dial tone, rings again upon hang up.
Hunting for additional parameters to change, I found another CPC setting on the Physical Parameters > Phone Port > Calling Features section.
GenerateCPCSignal: "For inbound and outbound calls" --> "For outbound calls only"
Success!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
The phone rang, was answered, and we could talk!
OK, now I need to reset some of the parameters that I've been playing with back to their defaults....
I reset 3 of the 4 PSTN Disconnect detection parameters as follows,
DetectCPC: no
DetectPolarityReversal: yes
DetectFarEndLongSilence: yes
DetectDisconnectTone: yes
This broke things, and we were back to ringing followed by a dial tone again.
So I disabled the DetectPolarityReversal again as follows,
DetectCPC: no
DetectPolarityReversal: no
DetectFarEndLongSilence: yes
DetectDisconnectTone: yes
Successfully received a phone call again!
I reset the following 2 parameters to their defaults,
RingValidationTime: 256
RingIndicationDelayTime: 512
This again broke things, and we were back to ringing followed by a dial tone.
RingValidationTime: 100
no change, ring followed by dial tone
RingValidationTime: 256 (default)
RingIndicationDelayTime: 512 --> 256
Success again!!
Ran out of time to try resetting more parameters. So at the moment, we have the following 5 settings altered on the OBi110:
Default --> Now
Interfaces > Line
Line Port
Ring Delay: 4000 --> 0
PTSN Disconnect Detection
DetectCPC: yes --> no
DetectPolarityReversal: yes --> no
Ring Detection
RingIndicationDelayTime: 512 --> 256
Interfaces > Phone
GenerateCPCSignal: IN & Out --> outbound calls only
