How to prevent outgoing voip fax calls?
<p>Is it possible to make a condition of outgoing VoIP calls on Asterisk?</p>

<pre><code>if(the receiver is a fax){
  don't start calling;
} 
</code></pre>

<p>If not, can we log(save) outgoing fax calls(with call info like time, duration, channel, location) into a file somehow?</p>

<p>Thank you in advance!</p>
