Use of the Instant Fax ATA system requires you to purchase a proprietary ATA from THREE PBX. To place an order, please contact us at 1866-771-(RING) 7464

Although it is possible to send faxes through any SIP ATA that is registered to the PBX using T.38 or G711 pass-through, these methods do not always satisfy the heavy fax user. This is a reflection of the fact that fax machines are especially vulnerable to latency and jitter. As a result, network problems that may not impede a regular voice call often interrupt a fax transmission and result in a dropped call.

The Store-and-Forward ATA solution allows faxes to be buffered before being transmitted to an analog fax machine.

• For Inbound (DID) calls, faxes are received in the THREE PBX data center (where last-mile latency and jitter issues are not a concern) by a Store-and-Forward fax server and then transmitted to the ATA using a file transfer protocol that is not susceptible to latency and jitter concerns. Once they are received by the ATA, they are relayed to a local fax machine that is connected to the ATA with standard RJ-11 cabling.
• For Outbound (Termination) calls, faxes from a local fax machine are intercepted and stored by the ATA and then transferred to a Store-and-Forward fax server in the THREE PBX data center using a file transfer protocol that is not susceptible to latency and jitter concerns. From the fax server, they are relayed to the PSTN using high-bandwidth SIP connections.

FAX ATA transmission (TLS encrypted) is considered as HIPAA compliant for sending or receiving faxes. HIPAA compliance requires policies & procedures.  A technology solution alone is simply not enough. Please consult with your THREE PBX support team if you have any questions or concerns about HIPAA compliance.
