Hi Christoph,

its easier for the mailinglist members to help you,

if they see that you tried something and show for example your config snippet where you have issues.

Right now its very hard to tell what to do.

So "i use configuration like in the shipped one with kamailio X.Y.Z and i didnt get the point how to identify my freeswitch as trusted for outbound and i used the default config https://github.com/kamailio/kamailio/blob/5.5.3/etc/kamailio.cfg#L566 and didnt get pstn route working."

As an example.

Kind regards

Karsten
