Getting a UK PSTN line to work with OBI110
Stewart:
It seems that you've covered everything, so I've no idea what may be wrong.
1. Confirm that firmware is up-to-date.
2. CallerIDDetectMethod should be FSK(V.23).
3. Try changing RingThreshold to 13.50-16.50 and/or RingValidationTime to 150.
4. If no luck, report what is shown under Line Port Status, when idle and when it is being rung.
Ostracus:
This may have nothing to do with it, but aren't some telephony equipment sensitive to an incorrectly wired jack (polarity reversal, red to green, green to red)?

Thanks Stewart, those settings helped. I paired the device to OBITALK and I think it screwed my UK LINE settings up. Your suggestions have got me working, though the ring tone is slightly off and the phone carries on ringing a couple of times when the caller has already hung up, so I think some other values are still "out"..
Any idea where I can get to see all of the default LINE settings for the UK build?
Ben.

This is the closest thing I could find; the numbers are there but the parameter names are of course all different. If you figure out the correspondence, you should be able to get the proper call progress tones, ring cadence, etc.
However, when an unanswered call is abandoned, the OBi has no way to tell, other than not detecting ringing for a while, so there will always be a delay before the phone port ringing stops. For the default (US) settings, this timeout needs to be > 4 seconds (default American ring is two seconds on, four seconds off). I don't know whether this parameter is adjustable -- I don't see anything that has a plausible name and value. If it can be changed, I suppose ~2.5 sec. would be suitable for UK.
