[Freeswitch-users] Issue with auth-calls false

I am having trouble creating an unregistered external gateway in FS. I went through the wiki and found that auth-calls and ACL's looks like the proper way to achieve this. I set auth-calls to false in both internal & external, added an ACL into domains to allow the cidr of the gateway in question. However after the gateway sends the Invite, FS always sends a 407 Proxy Auth back to the gateway. I checked into the IRC channel and one or two nice folks reviewed the config and said they thought it should be working, but the call still fails on Proxy Auth 407. The SIP Trace, external, internal & gateway profile from the test system are available at http://pastebin.freeswitch.org/21443 All suggestions are welcome, Trevor
