Incoming calls on pots line port not ringing through to the phone.

I am being very specific here:

As you are remote can you ring the PSTN line and look at Status > Call Status while you carry on ringing. Does a call show up there?
This is not the same as:
Quote
Status > PHONE & LINE Status > Line Port Status > State => Ringing
The first will only show ringing if all the configuration parameters are met. The second will show ringing for any incoming a.c. voltage.
Interesting... you're right, I did misinterpret that. I've never looked at that item during a call, and otherwise it is just blank.
I just tested this on *my* unit, and I see the ringing & caller-id info has been passed from terminal 1 to terminal 2. I wonder if it is being passed on my parents unit. I may not have an opportunity to test this in their place until next week, but if it fails to work while here, I can look at it.

Well we don't like unsolved mysteries here, so I'm relying on you doing a Sherlock Holmes on this one :)
I'd sure like to get it resolved too. I'm trying to simplify things for my parents not make things more difficult.
Speaking of unsolved mysteries... I may have a solution for some unexplained reboots... but that is for another thread! <tease!>

I was not aware that the OBi110 used different ring patterns for SP1 vs line. I only use the line input on mine for 911 access and to route my incoming cell calls out on SP1 (aa > google voice). Is the ring pattern for SP2 also different from SP1?
Yes, by default. You can keep the defaults or change them.

Is the OBi110 sensitive to the ringing pattern? I'm not sure, but I think the PBX in the retirement home might generate a double ring.
Probably, but not vary sensitive; your story is the only one I have seen like that. Since the OBi flashes a ring, and the call status shows a ring, I think, it is fair to say the OBi110 detected the ring.

The current (and hopefully temporary) solution has been to have the retirement home's POTS line on several phones, and the OBi's SP1 (google voice) on it's own phone.
My understanding of the OBi110, is that in the event of a power failure, a relay will close and pass the POTS line through to the phone port. Is this correct?
No. The exception is the originals have a relay that does that desireable thing. But the newer units do not have that really, so no power means that the phone port on the OBi is dead.

Hmmm... that IS a problem. I had counted on my parents phone service always being available, even in a power outage. I'd prefer to not add to their instructions & possible confusion in an emergency... use this phone, not that one, etc.
Is there some easy way to determine which OBi110 units have the relay... other than configuring it and pulling the plug?
Can a missing relay be installed in the later units?

A solution to the emergency phone might be to place a 2-way splitter on the POTS side of the Obi so that the pots line splits to a phone AND the Obi. The phone would have the ringer turned off. This phone could always be used to dial out (if desired) or in an emergency. While not as convenient and any other phone in the house being able t odial without power, it would suffice.
Simple external relays could be used to switch the POTS line to the phones in the house to bypass the Obi if necessary and not have to open the Obi.
If you were just trying to switch between the Pots line going to the Obi or an external telephone, a single DPDT relay would suffice. However without designing a solutions, my first thought is two DPDT relays are needed because you need to switch both pots wires (and I don't know if there is a common path inside the Obi with no power) and you also have to open the phone side of the Obi and not apply ringing voltage to the phone port.
(Note: As I thought this out, I looked up a 4pdt relay and designed this. It is untested but looks like it would work)
120 volt 4PDT relays are fairly cheap although you might be able to find cheaper ones at dc voltage power them with a wall-wart (power supply) if you have one to spare. We are talking perhaps $10 for the relay, maybe a bit more, some wire, some RJ11 jacks, solder and a small plastic box.
In this diagram, when there is no power to the relay, the pots line comes in, goes to the Common terminals and because the relay is NOT energized when the power is off, the NC connections are used, bypassing the OBI. When power is applied, the POTS phone line goes into the Obi and back out to the house wiring.
Sorry for the crude diagram, but it's been a long day.

Lavarock – neat design! If people are happy to use a soldering iron, then the relay could be powered from the same 12v d.c. power supply that powers the OBi. The relay coil will consume very little power, so it should not be a problem.
I have two OBi110s both are Hardware Version 2.8. Both have the internal power fail relay. More info here:

To test you only have to remove power from your OBi110. If the relay is present you will hear POTS dial tone when you pick up the phone attached to the OBi110. No configuring is required. Powering down should not lose any configuration you have.

Since the OBi flashes a ring, and the call status shows a ring, I think, it is fair to say the OBi110 detected the ring.
In this case I don't think Status > Call Status has been reported yet. I have spent a lot of “head-banging-on-wall” time getting various POTS / PSTN services working on OBI110s. Some odd stuff like GSM gateway devices etc. Various indicators and Status readings show what might be coming in from line such as ringing or CallerID. However, I have found that the only reliable indicators that the OBi110 has accepted and processed these things are if the show in Status > Call Status or Status > Call History.
The OBi110 can be sensitive to the ring pattern coming into it from the POTS service on the Line Port. This has nothing to do with ring patterns generated to ring the phone attached to the Phone Port. This still looks like a “Ring Detection” problem to me. If the PBX generates an odd ring, then this setting should be looked at:
Physical Interfaces > LINE Port > Ring Detection > RingValidationTime
There may be another complication here (not that you need another one!). The PBX will probably send one ringing pattern to the OBi110 for an internal call and a different pattern for an external PSTN call. I wonder if either works just now.
When testing remotely Status > Call Status is your friend – look at what it shows while the call (ringing) is ongoing. At least you will not be disturbing your parents – well not until you get it working ;)
