Side note: There are free online fax services. The document is uploaded from your computer and faxed to the appropriate number. Scan the docs (if not already on the computer) with your phone. Save them to google drive or email them to yourself. Then use something like myfax.com or efax.com to fax them for free. Source: over 2 years ago
I am wondering if there is a similar fax server software that you can install in your server and then connect your fax machine or receive and send virtual fax like efax.com (they charge 18 dollars a month). Source: about 3 years ago
