I have a BT1110 Single phone that was bought 5 years ago. When I tried to call someone on it, it says “Line in use”, and then when I just press the call button, it asks “Join existing call?”
When I restart the phone and I was just quick enough to call that number, but then I just hear... nothing. I called it on my mobile, and it made the “rrr-rrr” sound, but the BT1110 did not ring. When I plugged out the phone line cord (not the charger) then I called, it still made the “rrr” noise but it did not ring either.
When I plugged out the charger and set the time and date again, yet it did not solve the problem. The phone bills are set up by TalkTalk.
Welcome to this user forum for BT retail customers.
All I can suggest is that you call the product helpdesk, the number should be in the manual.
As BT Retail are not your provider, it would be a good idea to try a different phone, just in case you have a fault with the line, or TT have a fault in their equipment, in which case you would have to speak with them.
The one on the bottom of the charger that ends in 2182? OK.
