Help! Line Port Status constantly showing as "Ringing"

<< < (3/3)

1. Not clear which of these is the CallerID problem:

- the OBi110 is not getting the CallerID from the line.  Check by looking in the OBi's Call History.  (Local GUI only.)

- the OBi is getting the CallerID but not sending it properly or at all to the phone.

- the OBi is sending correct CallerID to the phone but the phone is not showing it.

2.  You can try increasing the RingFrequencyMin and/or decreasing the RingFrequencyMax.  You can increase the RingThreshold.

3.  I'm still somewhat suspicious that your line has an issue but that is not simple to diagnose. :-(  CallerID should not be be sensitive to line polarity and, in spite of what the normally reliable Ianobi wrote, should a reversed line should not cause false ringing.

4.  You didn't answer my DEL question.  And is it just a phone line or does it also have xDSL on it?

Just called Plusnet business and guess what, the caller id was switched off. I wasn't aware there was a feature to switch off called ID. Plusnet had no answer as to how it was switched off. They said it will be on 24 hours will test tomorrow and report back.

I agree something is weird with the line there. OBI110 works perfectly at home but when connect to the the business premises's phone line it behaves intermittently. Yes as I reported above the caller ID issue was related to being turned off at the exchange - so yes you are correct polarity reversal does not cause called id issue. In regards to the connection between polarity reversal and constant ringing, before the A and B port were incorrectly connected, I used to get this false ring all the time, now it is zero on most days two or three times on some days. So even if the polarity reversal does not imapct ringing somehow it is looking better now.

I just called Plusnet technical support and the lady said it was a coper wire coming into the premises. So she said no PBX or DEL. Not sure how much I can trust her. All I know is that the business premises is on the ground floor of a block of flats (more than 15 flats there) . I will call the landlord to find out but I doubt even if he would know anything about this.

Many thanks for your response

Just tested and Yes caller id is working now and hoping that this false ring don't happen more than once or twice a day

Okay, I did a little bit of thinking and now I am convinced that the issues with my OBI110 are resolved . To summarise, so others facing the same issue can be benefited.

1) To start with, I only had one issue - The OBI would work fine for few days and then suddenly the it will send false rings to the phone. When it used to start happening, it would be almost nonstop until you completely unplug the OBI.

2) I stumbled across this thread and found the suggest to reverse the polarity of the BT socket. So I swapped wire on the port A of the BT socket with port B and Wire on B with A.

3) I was still be scary of the OBI misbehaving after sometime, so I updated the inbound call route in line1 so that it would forward all anonymous call to just my mobile, all other calls to three devices; a)phone port of OBI, b) my wife cell mobile and c) my mobile after an 8 second. This is so that the false ring soes not create havoc at business and once I receive the calls I can try and check the call status etc on OBI.

4) I think it worked great for few weeks and then suddenly the phone stopped ringing at all for few days. This is ow can be explained by sudden switch off of caller id by Plusnet.

5) So as the called id was turned off at Plusnet end, all calls were diverted to my mobile and al the while I was thinking  that the OBI110 had started sending false ring again. Now I think they were only few phone calls a day, which would have been actual calls but because there was no caller id they were just getting forwarded to my mobile and hence no calls were received at the business premises.

So I think the OBI110 was working fine since I changed the polarity of the BT line (also testing voltage today to ensure the A (to 0V) and B (to -52v) ports are connected to the correct wire). It was the  the called id that got turned off at Plusnet end made me think that the OBI wasn't behaving correctly.

Finger crossed, the OBI110 shall be working now.

A big thanks to drgeoff and Ian for pointing me in right direction.
