Welcome to our community and thanks for posting. Firstly nobody ever knows there own number so you are not alone.... 🙂
To get your landline number the easiest way to do it is call your mobile number from your landline and this will show on your display screen. Alternatively dial 174 or 175 and your number will be given to you over the phone.
I cant dial put. Keep saying number not recognised. Got 2 sockets. Put it on 1 and get a dial tone. Put it in the other which seems to be linked to where the cables come through for virgin. Screen just says check line.
Sorry for the confusion, we thought you could not get your telephone number, not that you cannot dial out. When did you have the line installed?
What happens when you place the phone back in to the socket with the dial tone? Is this when you get the message number not recognised? Do you get this message when you call any number or just once certain number?
