My caller display has stopped working, any advice please?
Quote from: kmw350 When the BT engineer visited, I'm sorry to say that he described caller ID as a bit of a black art, and felt that not much could be done about it.
Oh dear, that doesn't say much for Openreach training.
Quote from: kmw350 My gut tells me it is a local exchange problem but what do I know?
My gut says the same!

Somehow I don't think I'd get past the exchange door...
Still, I could at least check on whether the signal is actually appearing on your line. Who knows, maybe you're local to me... PM me if you like.
A little googling suggests that BT can be pretty useless in solving this kind of problem - this BT forum thread makes depressing reading.
On a more positive note this thread contains the following -
Well - the fault is now fixed, thanks to an Openreach engineer who took our two new handsets down to the exchange today, tried them on our line down there and found neither worked.
Bottom line is that the Broadband was interfering with the CLI. Apparently there are two types of Caller Display units - analogue and digital. The cheapies (like those that display a single line of data) are usually analogue but most devices (such as handsets) are digital.
The analogue ones worked OK but the digital ones didn't until some equipment was changed over. He told me that if we didn't have broadband at the house, then the digital handsets would have worked, but when there is broadband the phone signal takes a slightly different route through the exchange equipment and the issue was there.
Something to do with the voice/broadband separation filtering I would guess. Maybe Matthew Wheeler could pursue this line of enquiry with BT?
Meanwhile, I've got a collection of stand-alone analogue display units here - PM me if you'd like me to post one for you to try.

Is your caller display still not working correctly?
Ben,
NO it is still not working, and has not worked at any time since I lost it back in August.
Please please can't someone get this looked into properly? How hard can it be?
Thanks
Update - no change at this end, still no caller ID
@kmw350 if it's any comfort I lost my caller ID a year or more ago and had it reinstated by the method proposed with no loss of service or changes. 
My ID had worked for years till I screwed it up with the hashtag thingy. The system is somewhat flaky but IMHO it's stand alone and there's a minimal chance of changes to caller ID affecting broadband or telephone services.
