How fax over internet works

Internet fax uses the T.38 protocol (Fax over IP, FoIP) to transmit fax data over IP networks instead of traditional phone lines. Modern online fax services like Faxend handle this seamlessly:

  1. You upload a document via HTTPS (encrypted internet)
  2. Faxend's servers convert the document to fax-ready format
  3. Servers transmit to the recipient via T.38 over the internet
  4. At the recipient's end, the T.38 traffic is converted back to traditional fax (T.30 over PSTN) if their service requires it
  5. Recipient's fax machine or service receives normally

You don't see any of this complexity. From your perspective, you just upload, enter number, send.

Why skip the phone line

  • Cost: Phone lines are $20 to $40 per month for many providers
  • Setup: Activating a phone line takes days, requires installer in many cases
  • Reliability: Phone lines fail, especially during weather events
  • Mobility: Internet fax works from anywhere; phone line is location-bound
  • Modern infrastructure: VoIP and fiber networks have largely replaced traditional phone lines
