Diagnosing Faxing Issues

If you're using a traditional fax machine, the fax line coming out of the fax machine will more than likely be connected to a Fax ATA. A Fax ATA converts an analog fax signal into a digital fax signal that can travel over the internet. The most common Fax ATAs used by Kontak Retriever will be either a Grandstream HT812 or Cisco SPA 122.

If you're experiencing issues faxing, the first step would be to power the Fax ATA off and back on again.

If you're still experiencing issues faxing after powering the Fax ATA off and back on again, we recommend you try the steps below:

• Call the fax number you're trying to fax. You should hear a fax tone, if not, there may be an issue with the fax number you're trying to send to.
• Force uLaw on the Fax ATAs extension. Faxes will NOT work over g729. (A Kontak Retriever technician can check this for you if you do not know how to do this.)
• If using an eFax account, make sure you are logged into the correct UCP/eFax Account that your fax line is associated with. 

The Fax Machine should have the following settings configured:

• ECM: Disabled
• Speed: 9,600 Baud (force a slower speed)

If you've done all the steps above and are still having trouble, please contact Kontak Retriever Support.
