Real T.38, not fax noise over a phone call.
A fax machine encodes a page as tones. Most internet phone services carry those tones the way they carry speech: through a voice codec, over a connection that tolerates a lost packet because a human ear does not notice one. A fax does notice.
T.38 is the international standard for fax over IP. The gateway demodulates the tones back into the page data they encode, carries that data as IP packets with redundancy, and re-modulates it for the machine at the far end. What crosses the network is the page itself, not a recording of it.
All ReliaFax transmissions use T.38.
What crosses the network
- Audio fax over a voice codec
- Tones re-encoded as speech. Jitter and packet loss corrupt the page, and a corrupt page is a failed page.
- T.38 fax over IP
- Page data, sent with redundancy and re-modulated at the far end. Designed for a network that drops packets.
What you get with a number.
Every plan carries one fax number, email-to-fax, and fax-to-email. The rest depends on the plan you pick.

- Fax-to-email
- Incoming faxes are converted to PDF and delivered to your inbox in seconds. No fax machine, no missed pages, no paper jams.
- OCR and search
