Fax to Fax ATA

Pangea’s VFR Fax to Fax (Internet Fax from end-user’s fax machine) service provides a very reliable Internet fax service.


t.38 and Internet Faxing

t.38 the ITU recommended standard for sending and receiving faxes over the Internet, was designed to send raw data over networks for fax transmissions.  In theory, this should work fine.  The reality, as anyone that has tested t.38 over the public Internet can attest, is at best, unreliable.  Jitter, packet loss and PCM Clock sync issues often cause these faxes to fail and the longer the fax, the more likelihood of failure.  For businesses that rely on fax as an important way to communicate with their customers and business partners, it is clearly a costly, frustrating and unacceptable solution.

Pangea’s Solution: Taking t.38 out of Internet Faxing

With Pangea’s Internet Fax to Fax solution, end-users never need to worry about packet loss, jitter or PCM Clock sync issues creating fax failures.  Our solution does not utilize t.38 at the end-user’s location.  Rather, our ATA (Analogue Telephone Adapter) is loaded with our proprietary software essentially turning the ATA into a local fax machine accepting the fax from the end user’s fax machine locally, encrypting and compressing the fax data locally and transmitting the fax to the Pangea Data Center.  This process is not affected by jitter or packet loss and works perfectly well over the poorest of Internet connections including Wi-Fi and satellite.

Once a fax a fax is received from the end user’s fax machine/ATA in whole at the Pangea Data Center, Pangea’s Smart Routing will attempt to deliver the fax to its intended destination through a variety of ‘fax sensitive’ carriers employing auto-retries based on algorithms designed to give the highest delivery success rate possible in the shortest amount of time.  Our success rate for fax delivery is higher than one would get with a standard POTS line connection. Confirmation is then sent to the end user via email and/or fax machine as to the result of the sent fax transmission (success/failure).

Incoming faxes, destined for the end user’s fax machine, work in the opposite direction.  Incoming faxes are first received in whole at the Pangea Data Center where the end user’s ATA connects securely over TLS encryption and then delivered to the end user’s fax machine.  Incoming faxes can also be delivered to the end user’s email.  If the end user’s fax machine or ATA is off-line or unable to receive, faxes can queue until such a time the ATA and fax machine are available so senders never get a busy signal and end users never miss a fax!
