How to Configure NVFax on FreePBX

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.

Asterisk Check T1 Status Because Faxes Sent Via Hylafax Fail

If you have a Asterisk system being used for sending and receiving faxes and all of the sudden the faxes all start failing with various error messages the first thing that should be checked is the status of either the analog telephone lines, the T1’s, or the SIP provider you are using as a outbound proxy. Below I describe some of the error messages that may be received via Hylafax in this example as well as how to check the status of the T1’s themselves to make sure that there are no alarms present before you have to get into troubleshooting Hylafax in detail.

Set Time For Polycom SoundPoint Phones Via CFG Files, Override DHCP NTP Settings For SoundPoint Phones

While working on various things in a Asterisk VoIP deployment earlier I needed to override the DHCP NTP settings for a specific phone because this particular user was remote. The configuration file for their phone was actually using a different outbound proxy and SIP registration server address so they could operate remotely. One of the issues pointed out to me was the fact that the phone’s time was never correct and after some basic investigation I was able to locate the issue which is described below as well as how to override the DHCP NTP address settings via the Polycom SountPoint CFG (configuration) files.

Include Underscores While Using Markdown Without Them Being Bold Or Italic Indicators For Text

I am fairly new to Markdown and have really just been becoming more familiar with Markdown while posting here on Question Defense’s [Engage][1] site. So far I really like Markdown and have been impressed with how user friendly it becomes as you learn the Markdown tricks as I call them including asterisks or underscores for bolding or italicizing, brackets for links/URLs, and numbered lists simply using 1., 2., 3., etc. While the Markdown learning curve has been fairly steep for me
An issue I ran into on my last post was the fact that I was posting some PayPal variables that included underscores within the variable.
