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.
A client of mine had a Cisco 2811 installed before I started working for them so I had to go over the configuration to become familiar with things. One of the Cisco IOS configuration items used was translation-rule which will allow 10 to 15 Rules to be created under each translation-rule. In this scenario they were using translation-rule to forward external DID’s from their telco provider to internal extensions. This works fine except for the fact that if you have more than 10 (in this case) external numbers you won’t be able to continue to forward them to internal extensions without complicating the configuration using multiple dial plans, etc. The easiest way to get away from the translation-rule being used in this way is to assign t he external DID telephone numbers as secondary numbers under each extension configuration as explained below.
