Twilio has a Fax API: https://www.twilio.com/fax

We had issues faxing rural areas through Twilio, like their SMS offerings (which lack shortcode support) it seems to be a partially baked solution. I asked them about it at SeaGL in Seattle, and the staff at their booth had few suggestions.

Idk about the fax issues in rural areas, I'm sure it's possible cause fax is hard, but Twilio definitely has SMS Shortcode support.
