I still got my yellow bt butt phone as they would call it 

Me too nothing like being 100% sure that the phone line is present and working and that you can phone from it. Its part of the diagnosis, and I would not be happy about condemning anything without being sure that I have explored all avenues.

IA if there is a ADSL filter fitted you would have seen it for sure. Mind you if it is the phone line and they change the panel, and it still doesn't work you have one a free panel, they wont put the old one back as it will take too long (Lab cost v Kit cost = cheaper to leave it there)  and they cant charge you for a new one because there was nothing wrong with your old one.  

Good thing on test phones is also the polarity switch , goes red or green so by can't blame installer after for wrong connections lol

 

I used to find some engineers get caught on the ringer not realising the test phone acts as a master so will always ring on the extension with number 3 being connected

Get a new panel

New engineer 

New company 

Or new external dialler 

 

And your done 

 

Reality many alarm panels need to be changed out move with times , some decorate every 10years so a new security system every 10 is good on residential aswell
