SkySwitch supports faxing with a SIP ATA on a best efforts basis only!
Because fax machines rely on the analog representation of a digital signal (what you hear as a "fax tone") they are susceptible to deviations in the fax data transmission. In practice, this means that faxes are often interrupted by jitter and latency in the last mile (the portion of the call path between the switch and the end user's fax machine). This level of unreliability causes most VoIP service providers to avoid deploying faxes using SIP ATAs.
We strongly recommend that Resellers deploy faxing using the SkySwitch Instant Fax ATA or Instant Fax Portal services.
Use of the Instant Fax ATA requires you to purchase a proprietary fax ATA from SkySwitch. To place an order, please go to the SkySwitch Store available from the Dashboard Menu.
It is not possible to Fax on SkySwitch with a BYOT Number. The DID must be active through SkySwitch in order to use any of our faxing methods.

Note: We have found Fax ATA outbound faxes to devices with a Fax 'Stick' can be problematic and require configuration changes to the receiving fax machine for successful transmissions at times.
