[Freeswitch-users] How to not send 407 if username not recognized

Hi all, Currently, FS sends back 407 (Authorization needed) to a REGISTER or INVITE even though the From: username is not one in our directory config. Is there a way to configure FS to not send back 407 if the username in the

From field is not recognized?

I’d like to not give scanner bots any clue that there is a SIP proxy. Thanks!
