Fax To and From the Cloud
etherFAX is an aggregation of virtual ports that allows you to simply to send and receive fax communications via the cloud. Providing an infrastructure as a service (IaaS) platform, etherFAX enables you to utilize your existing fax server solutions to send and receive faxes. This allows you to eliminate the need to provision and/or maintain costly telecommunications connections or purchase expensive fax boards, servers and related services.
By leveraging the cloud to terminate inbound and outbound faxes, all images, transmissions and property information is transparent to etherFAX and stored on your server within your firewall.
etherFAX allows you to eliminate the recurring monthly phone line expense and only pay for faxes sent and received through etherFAX at a fraction of the cost.
Is it FoIP? Not Exactly
The etherFAX communications protocol (ECP) is a proprietary, real-time encrypted communication transport between your fax server and the etherFAX data center ensuring 100 percent reliable communications. etherFAX does not experience the issues that SIP T.38, G711 or FoIP face today.
Unlike some demanding communications such as T.38, our services are simply Web-enabled and designed to operate in the most unreliable of environments using minimal network bandwidth. The customer server simply provides the “what” and “where” it needs to be sent, etherFAX does the rest and reliably manages the fax transmission from start to finish.
How etherFAX Works
Security
Security is a clear differentiator when comparing other outsourced fax services to etherFAX. etherFAX incorporates a multi-level encryption/security system known as a “defense-in-depth” approach. It is a layering tactic, conceived by the National Security Agency (NSA), as a comprehensive approach to information and electronic security.

Outbound
A fax job is submitted to your fax server, where the image is rendered, stored and then transmitted via secure HTTPS to the etherFAX data center for processing. Upon completion of the fax, a confirmation is sent back to the originating server, resulting in a notification to the sender of the fax. This process only requires an Internet connection.
Inbound
etherFAX issues you a dedicated fax number(s) and/or can use your existing number, and the faxes are received at the etherFAX data center. Each fax is identified as your fax, based upon the number that was called, and transmitted via HTTPS to your fax server. Once received, the fax is delivered to the appropriate person's inbox, and they receive a notification (email most often) that a new fax has arrived.
All faxes are never stored at etherFAX; they are simply processed and stored on your fax server.
