Customers may sometimes raise enquiries on how to block unwanted incoming fax numbers or spam faxes. This article provides important information on handling unwanted/junk faxes and provides a useful workaround to effectively block unwanted incoming faxes.
GFI FaxMaker Online does not provide an option to directly block incoming faxes. In order to facilitate the feature that allows simultaneous faxes to be received on a single fax number, we do not assign our numbers to a specific trunk group/line. Blocking fax calls would require the inbound number to be assigned to a single line.
For this reason, GFI FaxMaker Online does not support blocking an incoming fax number. This feature is only available for GFI FaxMaker (on-premise) application through the Junk Fax Filter.
As a workaround, we recommend that our FaxMaker Online customers make use of the opt-out contact information that senders in the U.S. are required to include on the fax. In addition, you may register your number on the National Do Not Call Registry at donotcall.gov.
