Remote Fax Answers Then Fails
The remote machine answers the call, but the Fax transmission sometimes fails to complete.
Initial Actions
• Check that Fax is enabled and configured properly for the local phone line.
• Check the target Fax number. If the number is in memory, is it saved correctly?
• Call the target Fax number from a desk phone and confirm a Fax tone response.
• Check Fax cord condition and connections between the system and Fax line.
Primary Causes
The Fax line quality is poor for Super G3 transmission speeds (default).
Troubleshooting Procedure
Fax Does Not Answer
The system does not answer incoming calls.
Initial Actions
• Check that Fax is enabled and configured properly for the local phone line.
• Check that the phone line supports Fax protocols.
• Check Fax cord condition and connections between the system and Fax line.
Primary Causes
This is usually a ring detection problem, or an unusual or low-quality ring signal. A high Answer
Delay setting, Junk Fax Prevention, or Fax Receive settings might impede inbound calls.
