I too had the same problem no dial tone, I checked evertyhing like they tell you and this made no difference. Then I went and had the line tested and there was a problem with the connection. People were phoning but I just could'nt hear the phone ringing and no dial tone. They booked a engineer and it was all done the same time as "Verdin".
