Hi i've had a few people tell me their mobiles won't connect to my bt landline.
i've been asking people to ring to find out if there is any particular network or pattern as to why it's happening. Bt have checked the line and even tried ringing me on 02 which worked. anyone heard of any similar problems? i wondered if it could be to do with the telephone pref service which i signed up to not so long back.
appreciate any help thanks
