We been using rightfax to send fax for while using our T1 provider data line. Now we moved to a new office and our manager switched internet line from t1 to Comcast cable. Now we are unable to send fax using these lines. I tried to connect a regular fax with those line and it does not send fax.
We called guy who setup phone and he has we should not have any issue sending fax using any phone line. I'm not a phone guy, not sure I understand why cant I send fax using these lines. Can comcast provide data line(analog line). Also can rightfax send fax any other method?
