[Freeswitch-users] How to check whether incoming call is authenticated

In our external.xml: <domains> <domain name="all" alias="false" parse="true"/> </domains> <param name="auth-calls" value="false"/> It means, that everyone can make call from outside to our freeswitch. Is it possible to know if caller already authenticated in our freeswitch? (in a dialplan) Thanks. -- Arthur
