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

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.
I expect that a single DPDT (the part connected to the the Phone jack) would suffice. I expect the Line jack on the OBi110 to represent close enough to an open circuit with no power applied.

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.
Lavarock7 - While an external relay would indeed work, it seems pointless when the OBi110 has the capability to be easily modified with just a few parts. Much cleaner. I'm already getting push back from my parents about all the hardware & cables for cable modem, router, OBi, network cables, switch, phone lines, computer cables, wall warts, etc... I don't want to add to this already horrendous mess! ;-)

I have two OBi110s both are Hardware Version 2.8. Both have the internal power fail relay. More info here:

ianobi - Thanks for the link. It seems stooba has already examined this and discovered it is just a matter of a few missing parts. This should be a real easy mod... I just need to identify the missing components. I don't suppose you'd be willing to pop open one of your ver 2.8 units and carefully photograph the PCB?
Are the units with the gray tops the ver 2.8 hardware?

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.
I can check this status while the unit is here this weekend, but won't be able to do so with their PBX until next week when they return home.

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
I suspect you may be right. I think I did hear an 'odd' ring one day at their place... a double ring.

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.
So if I get it working for my calls from outside the PBX, I will need to also test for calls internal to the PBX. Thanks for pointing this out... now I just need to get one of their neighbors involved too! ;)

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 ;)
Actually I must disturb them, as I need them to disconnect a nearby phone and hook its cable into the line port of the OBi in order for me to test... and to then listen for a ring, if any.

gary,
Have a read here for more info from stooba and pictures:

ianobi:
I've had a poke around inside one of my OBi110s and the relay in question is:
http://uk.futureelectronics.com/en/technologies/electromechanical/relays/signal-relays/Pages/3310323-TX2-4.5V.aspx
Put one of these where the hole for relay K1 is shown on stooba's pictures and that's how it looks. As stooba points out, there are a few other questions regarding other components.
There is a misprint on the page the above link goes to. "Product Highlight" correctly states the coli voltage as 4.5v. Further down coil voltage is wrongly stated as 24v.
