Have tried removing the filters, still no joy. Perhaps the fault is with the Phone
Did you do as I suggested in my earlier post "try a different phone that has caller display."
Is the phone set to TB ?
Not sure how that will allow or stop CLI information?
Neither am I Dave,but Mother-in-law had a similar problem,I flicked it down to TB and it's been OK since,so it's worth a try.
There's a Dial mode slider button usually on the underside of the phone with options of "T" ,"PE" or "TB". TB is for tone dialling, long shot really but it might be worth experimenting with each setting.
Edit -- Does your phone require batteries ?
Is there batteries in the phone ? are they getting low ?
Try removing telephone from socket, remove batteries from telephone and leave out for 15 seconds and then replace,or If it's mains powered, switch the power off for 15 seconds, then switch power back on. The next incoming call should reactivate the Caller Display service.
Check that the Caller Display unit is not beside a cordless telephone. Caller Display equipment should be at least 1 meter away from each other.
Try another compatible phone,if it still doesn't work ask the forum mods to intervene for you by submitting this form
The main phone does not have batteries, although the cordless one does. I tried your suggestion of switching off but still no joy. The main phone is downstairs sitting next to the computer, the cordless phone is upstairs. I have filled in the form as suggested.
Thank you for trying.
You need to try another phone that has caller display or take your phone to someone who has the caller display facility. If BT attend and prove that caller display is OK (I suspect it is as *#234# says it is and no real chance a line fault would cause that) they will charge you £139 for the visit.
