Hi,
i am using tls + srtp without tls-verify-policy=all in internal.xml. i use tls-verify-policy none or out. if i set it all i can't connect to freeswitch. 
when i set to all and capture network with wireshark i get "TLSv1  Alert (Level: Fatal, Description: Unknown CA)". on client i am using csipsimple nightly build version.
Thanks in advance.
