No, it doesnt work, becouse we set in external.xml 

    <param name="auth-calls" value="false"/>

documentation (https://wiki.freeswitch.org/wiki/Sofia.conf.xml#auth-calls) says that "Value can be "false" to disable authentication on this profile, meaning that when calls come in the profile will not send an auth challenge to the caller."

We can receive calls, no problem, but for our needs we want to check who is calling - user is authorised or not.
