Before I called att yesterday if I held 1 I would get to the mail att voicemail system. If I then added my 10 digit # it would say something like, this voicemail account does not exist.
Hi. I am the original poster. When I dial the 10 digit phone number I get a busy signal. So neither of the proposed solutions will help me. I did change the phone settings to the 10 digit number and held 1 and still get busy signal.
