I just tried to send a fax. The number that I sent it to received the fax from me, but their machine could not open it, some kind of an error. I did a search, and found this thread. So I assume I can not send or receive a fax? Odd, even the cheap Magic Jack would send faxes. I do have a DSL filter attached, and still it did not work. Is there any other trick to sending a fax and getting it to work?
