Did you move your phone service from another provider? If so, then its possible that the number has not been ported correctly, especially if your mobile says invalid number.
We switched from one provider to BT in January, the fault on incoming calls was logged on 7th March and yes, before asked, we had incoming calls on our landline inbetween. The fact remains that nearly 21 days later we are still not receiving the service we signed up and are paying for.
If it has worked, then its not a porting error, so its should be possible to fix.
I have asked a moderator to provide assistance, they will post an invite on this thread.
They are the only BT employees on this forum, and are a UK based team of people, who take personal ownership of your problem.

Please do not send them a personal message, as they cannot deal with service issues that way.

Welcome to the forum and thanks for posting!
I'm sorry for the problems you're having receiving calls on your line. It's definitely a strange one!
No need to worry as we'll pick this up and get you sorted from here. You'll see the link to get in touch with us in my profile under the section "about me". You'll find it by clicking on my username.
Has this been fixed for you yet? If suffering the same (2 weeks so far), but I've been told (unofficially by an Openreach engineer) that it's a software issue at the exchange that BT have no fix for yet, so am interested in other cases of what sounds like the same issue I'm suffering.
