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.
TCtrace is like a brother to itrace and traceroute but it uses TCP SYN packets to trace. This makes it possible for you to trace through firewalls if you know one TCP service that is allowed to pass from the outside. Once again its a very simple tool like the last few I have reviewed and it has one specific function.
