Check your adaptors! Between the incoming line BT socket and the Obi line port you need BT plug to RJ11 "crossover" adaptor. Most of them are of the crossover type, but not all. The constant ringing is a often a symptom of crossed A and B wires.
Between the Obi phone port and your telephone you need a US to UK adaptor with capacitor. The capacitor is important as most UK phones are 3-wire devices not 2-wire like most of the world. (We Brits like to be a bit eccentric!). I use Maplin part VD36P.
I have been using an OBi110 in the UK for six months now and am a very happy customer. After sorting out the connections, you may wish to to consider UK style dial plans. That's a whole new subject for future posts!
Good luck and watch out for them pesky bears :)

Hi I am experiencing the same issue. The line port detects ring all the time and the attached phone keeps ringing. Can someone suggest the correct adaptor with a link that I can buy. I found three different variant in tool stations, but nots sure if anyone will be good for the job.
Single 34066 - https://www.toolstation.com/line-adaptor-t568b/p34066
Multiline Secondary 87417 - https://www.toolstation.com/line-adaptor-t568b/p87417 and
Multiline Master 38095 - https://www.toolstation.com/line-adaptor-t568b/p38095
Most modern phones available in the UK do not require the ringing capacitor. Try the Toolstation single one.
If you have a spare XDSL splitter filter you can use that to convert between a BT type phone socket and an RJ11 socket into which you can plug the lead supplied with the OBi110. Note that using this does NOT remove the need for any existing filter. Plug the second filter into the phone socket of the existing one.

Thanks for your response, i bought one from ebay with capacitor but you are right my phone doesn't need ringing capacitor.
My issue is that the OBI110 works fine at home for months. But as soon as I move it to my business premises, it will work fine for a day or two or even a week. But then one day it will start ringing on PSTN and then will keep ringing intermittently (sometime one after other).
So I took the suggestion from Ian above and swapped the A and B port on the BT socket and now while it does not do false ring on PSTN as frequently as it used to do ( max 2 to 3 times a day) but now my called id doesn't work at all. So i think i will need to swap A and B again so the called id works.
Is there any parameters in OBI that I can try so that it doesn't detect false ring. There is a phone connected directly to the PSTN line (in parallel to OBI) and no false ring is detected on this phone, so somehow OBI detects ring that is not there

Sounds like your business line may have a fault. Is it a DEL (Direct Exchange Line) or a PBX extension?
There are several settings for Ring Detection at the bottom of the Physical Interfaces, Line Port page.

Thanks for a super quick response. The question is why the connected phone doesn't detect any false ring and the OBI110 does sometimes. What settings do I play with on OBI110 to ensure that this false ring is not detected by OBI. In other words OBI behave much same like a normal phone when detecting ring on OBI line port

So I need some further investigation
1) First I wanted to make sure the A and B port of B Socket is correct, so I opened it. Solid Orange was connected to Port A and Solid Blue was connected to Port B ( note I had earlier swapped it and after the swap the constant ringing was kind of stopped - point made by Ian that constant ringing is a sign of Port A and B reversed). Just to ensure that the Port A and B are correctly connected I used the multiple meter and tested the DC voltage between A and B . I connected A to Black wire of multi meter and B to red wire and the voltage was measured to -53.2. So meaning the port A is 0V and Port B is -53.2V. According to various forum this is the correct BT line connection for Port A and B. - So all good here.
2) I also tested the BT to RJ11 cable between the BT telephone socket and OBI line port and I can confirm its a 2 pin cross over cable. i.e. pin 2 of BT socket connected to pin 3 of RJ11 and pin5 of BT connected to pin 4 of RJ11.
3) Now my caller id is not working anymore and It was definitely working before when this phone was constantly ringing and I don't think i have changed any settings on OBI apart from swapping the A and B wire (which fixed the constant ringing issue and also the voltage suggest A and B are now correctly connected) Does the caller id has any impact on the order in whoch A and B connected or what settings shall I try to get the caller if working
My Current Caller ID configs are (taken from OBI110 UK XML settings)
PHONE Port -> Port Settings -> CallerIDMethod = FSK (V.23)
PHONE Port -> Port Settings -> CallerIDTrigger = After Polarity Reversal
PHONE Port -> Port Settings -> Calling Features = checked
Line Port -> Line Port -> RingDelay = 400
Line Port -> Port Settings -> CallerIDDetectMethod = FSK (V.23)
Note-1: Pin 2 of the BT socket is the 2nd pin when you hold the connector with the connector at the top and wire at the bottom and you read the pins from right to left on the metal connector side - see in this photo https://www.google.com/url?sa=i&url=https%3A%2F%2Fwww.leadsdirect.co.uk%2Ftechnical-library%2Fpinouts-wiring-diagrams%2Ftelecoms-wiring%2F&psig=AOvVaw2nfs0NHBI642oODeW3PwLr&ust=1625053177875000&source=images&cd=vfe&ved=0CAoQjRxqFwoTCLDv9Y7hvPECFQAAAAAdAAAAABAD
Note-2: Similarly pin 3 of the RJ11 is the 3rd pin when you see the connector from the front and the locking notch is down and you read the pins from left to right - see in this photo https://www.google.com/url?sa=i&url=https%3A%2F%2Felectronics.stackexchange.com%2Fquestions%2F18009%2Fhow-do-i-do-the-6-pin-rj11-to-rs232-female-serial-adapter-wiring&psig=AOvVaw1uPAk3QxPEft_rbWw7K8mp&ust=1625053215819000&source=images&cd=vfe&ved=0CAoQjRxqFwoTCMCE2Z7hvPECFQAAAAAdAAAAABAa
