Is your network/firewall configuration permitting the ports for
UDPTL, runn the command: udptl show config<br>
<br>
<blockquote>UDPTL Global options<br>
--------------------<br>
udptlstart: 4000<br>
udptlend: 4999<br>
udptlfecentries: 3<br>
udptlfecspan: 3<br>
use_even_ports: No<br>
udptlchecksums: Yes<br>
<br>
</blockquote>
In your sip configuration for your 'mytrunk' peer have you set
applicable options e.g.:<br>
<blockquote>t38pt_udptl=yes,redundancy,maxdatagram=400<br>
</blockquote>
In your extensions.conf you could and probably should set the
following option prior to dialing the IAX channel, this is to enable
the T.38 gateway feature of Asterisk 11:<br>
<blockquote>Set(FAXOPT(gateway)=yes)<br>
</blockquote>
I have it working in my installation however I have incoming voice
calls too hence I use 'faxdetect' to direct the call to the 'fax'
extension.<br>
<br>
