When I try to send a manual fax , the 7640 dials its own number first and then the number being called. The result is always a busy signal . I know it is dialing its own number because that number appears on the screen follwed by the number I'm trying to call. There was a similar problem posted on (I think) this board but it never appeared to get and answer.
