Anything complicated about the history of your landline number , has it always been a BT number , and never ported to another company before coming back to BT, or is it another company’s number originally that is currently imported to BT ?
The person calling you that can hear ringtone but your phone doesn’t ring , calling you from another BT landline or a different landline provider or a mobile provider ?
Lastly , if you have dialtone from the hub , call 17070 and check the correct number is read out ( this can be in place of checking the router stats page or do that as well as )
It may be your phone is not compatible, however normally in these cases connecting it to the hub with a ADSL filter can make it ring to incoming calls as the ADSL filter replaces the missing connectivity ( this is usually needed with very old phones ) , otherwise as stated get a call made to you while you are waiting near the phone , while the caller is listening to ringtone (but your phone not ringing) , lift the handset anyway , if the call connects , you need a new phone, that’s if the ADSL filter hack doesn’t work .
