FIX: Unable to send faxes to certain numbers using a Quintum gateway and FoIP Standard Edition



ID: ZTN1895

This Zetafax technical note applies to:

  • Zetafax 2011
  • Zetafax 2012


Outbound faxes fail to send to specific numbers when using a Quintum gateway configured with FoIP Standard Edition. An error occurs during call initiation. This is more likely to occur in fax machines that also act as voice lines.


A fault was identified in the software which caused an incorrect fax connection tone to be passed to the receiver. This meant that the receiving machine, if not tolerant enough, would not be able to identify the call as a fax.


The fault was corrected in a hotfix.


Please contact your reseller or Equisys technical support to obtain the hotfix.
