I'm still very confused but always willing to learn. So how exactly did this phone work with the door lock?
Did it ring like a normal incoming call with the same ring pattern?
How did you then operate the door look from the phone?
You say "mobile works", what does that mean exactly? You can call your landline from the mobile & it rings as expected?
Hello again thanks for getting back.
The phone works normally receives calls same ring tone for house calls or entry door when it worked.
To operate the door the visitor enters the flat number this rings on my phone i click a number on the phone (number 5) and this releases the door.
The door entry unit having sent the number, our landline number,to our same phone Goes through the connection process and will ring the 1st number and it shows you it is ringing on a small screen and then connects.
But now it shows it is ringing in the screen but the phone is not connecting.
The mobile number works pay and go. This was registered by the company when i checked with them they put the landline in to but it does not work.OK end of the day we can use the door but i would prefer on the land line.
Sorry, I'm no wiser now.
If your phone does not ring for normal incoming phone calls, but did when you had an analogue line, then the only difference is that the phone is now plugged into the Smart Hub 2, which would point to the "ring wire" issue I mentioned. That is why BT have said you need a new phone, as they have said that older phones may not work. Try the microfilter first, and see if you phone then starts to ring on incoming calls.
I assume the door entry system must be programmed to call your home phone number, and then listen for a number "5" to open the door. I assume it calls your mobile number if it gets no reply on your home phone, is that correct?
OK, so it seems that the door system does indeed dial your landline. I would suggest that the next step would be to ask the door people how the system dials. Does it use a GSM module to make a "mobile" call or is it wired to an analogue or VOIP system? Then ask who their provider is. Once you know who & how the door calls are originating, post back here as it may help.
We have seen many reports here that after migration to DV, certain callers can't get through. That would be my best guess as to what's going on here. IIRC, this was as a result of an issue with the porting of your landline number to DV being somehow incomplete. This has required intervention from the forum Mods so hopefully on of the CLs can flag your thread.
You could also try calling BT again & asking for TMC (Technical Management Centre?) as there's more chance of actually speaking to someone who will understand the issue. But I'd suggest leaving the door system out of the conversation & just report that you aren't receiving calls from X once you know which X the door people use.
It's certainly less than clear, but that phone is under 10 years old so I wouldn't have thought it was a ring wire issue.
Let's await the next instalment!
As far as I'm aware @Lance3 hasn't said definitely one way or another whether calls from other sources ring normally. The mention of mobile in an early post gave the impression that calls from a mobile were successful but this may have been a misunderstanding if what was actually meant.
Perhaps @Lance3 could clarify if other calls can be received successfully. The implication is that they are otherwise I would have thought there would be no point in just posting regarding the door entry rather than the phone not ringing at all.
