Hello andie42,
Have you tried faxing a different fax number that you know is able to receive faxes? Have you contacted the owners of the fax number you are trying to reach to know if they are able to receive faxes? Have you tried plugging an analog phone into your fax line to see if you get a dial tone?
When I try to fax it dials the number but every time it gives an error and says 'No Answer'. I have tried from the pc and from the wk center. I'm lost!
