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

Nice investigation and writeup. I looked up CPC, and found http://www.sandman.com/cpcbull.html to give a good description.

Yep, I found the same reference. The interesting thing is that this article states:
"Battery Reversal hasn't been used in this country since they took out the last Step-by-Step CO switch."
Yet I found that if I did not disable 'DetectPolarityReversal', things would not work. So I'm guessing that the PBX implements polarity reversal!
I had previously tried just disabling this setting by itself, with no success.

GenerateCPCSignal: "For inbound and outbound calls" --> "For outbound calls only"
I don't think I would ever have thought of that. I don't remember it being an issue ever before in any country.
Normally setting RingDelay to 0 means the OBi loses the ability to detect CallerID on incoming calls as this comes in after that first ring in North America. However, this PBX is so weird that maybe it sends it before the first ring - standard in UK and some other countries. This will be obvious by looking at Call History.
If the OBi110 works reliably and your parents choose to keep it, then you might want to consider better digitmaps etc for them. It should be possible to prepend "9 pause" to outgoing calls and allow for internal number ranges.

As noted by both QBZappy and the portal, Build 2824 has finally been released. Whatever bugs existed in 2774 and 2776 may have been corrected in the 2781M that you said yours contained, but you may want to consider loading 2824 anyway. I wonder if the M might have denoted some sort of beta bug fixed version, anyway.

Thanks for the tip... I've now updated both my and my parents OBi110 to the 2824 firmware. I don't know what might have changed, but can't say that we've noticed any differences.
