[Freeswitch-users] How to distinguish between Authenticated sip and not authenticated users

Guys, trying to distinguish between authenticated SIP user and not authenticated, still no luck I would like to allow anyone to call my FS users via SIP, so there are registered users and everyone else so I have allowed <param name="auth-calls" value="true"/> <param name="apply-inbound-acl" value="allow_all"/> acl.xml: <list name="allow_all" default="allow"> <node type="allow" cidr="0.0.0.0/0"/> </list> Any call passes through, by always have [CHANNEL_CREATE] event variable_sip_authorized: true in event headers. But I would like to know if user is authorized or not. if I disable authentication by setting this to false <param name="auth-calls" value="false"/> all calls do not have any auth headers. Any clue?
