Earlier I received a call from a client wanting to know if their VoIP solution would allow them to receive fax calls that would convert a fax to email. After looking at their system the solution was fairly easy since they are running Asterisk with a FreePBX front-end. There are two options with FreePBX when setting up incoming fax lines which include NVFax or Zaptel. Having used both solutions in the past the NVFax option has always worked without issue and that is typically my default selection unless there are extra requirements. Follow the directions below to configure a Asterisk FreePBX DID for fax to email conversion.
