</div>I finally re-read the complete thread. When are you starting the VPN<br>
on your Asterisk server, before or after Asterisk has started? If<br>
after, and you are binding to 0.0.0.0, it is likely Asterisk is not<br>
actually bound to your tun0 interface. So, for a test, explicitly<br>
have asterisk listen only on the tun0 interface, retry your call.<br>
<br>
Or setup your tunnel, then stop Asterisk and start it again, that<br>
should cause it to bind properly.<br>
