How have you established that the phone doesn’t ring for incoming calls ?, is it simply people have said they called you but got no answer , when you know you were in at the time but never heard the phone ‘ringing’ , or you have called yourself from your mobile (for example) but the landline didn’t ring ?
Although it could be a ‘no ringing’ problem , it could also be that in effect incoming calls are not yet routed to your DV service even if outgoing calls are OK , a few things to try , call 17070 from your landline and check the correct number is read back to you , call your landline from a mobile and even if the landline phone isn’t ‘ringing’ , answer it anyway and see if the call is connected, reconnect your phone to the master socket in the same way it was before DV , call your landline number and see if it rings in the old socket.
I suspect it’s not ‘no ringing’ as such ( in that the incoming call is present, it just isn’t making the phone instrument ‘ring’ , but the migration of your number from the PSTN service to the DV service has not completed successfully leaving your number in limbo between the two services , basically incoming calls are disappearing into the ‘system’ and not presented to your DV service.
Is there any history to your landline number , like it was ported around different suppliers in the past , or has it always been with BT at the address you are living at ?
