[Freeswitch-users] Disable 401 and 407 for internal profile

Hi, I want to configure FS to not challenge calls that come in from an internal profile (internal network devices), meaning disable SIP '401 Unauthorized' and '407 Proxy Authentication Required' for calls that belong to internal profile. I changed 'auth-calls' parameter to 'false', in internal.xml file but FS still sends 401 method when a user attempts to register and it sends 407 when an invite comes in. It seems the parameter is for ACL though. Is there another parameter to change in order to disable SIP 401 and 407 methods? Thank you.
