[Freeswitch-users] Problems with initial setup - basic nat

Sat Apr 26 09:20:04 PDT 2008

The blind-auth is the important one here.
sipX always sends an auth header even before we challenge it so by nature
when FeeeSWITCH sees an auth header, it automaticly tries to qualify it in
the db.  I added that blind-auth option just for someone who had the same
problem.  When set at the same time as auth-cals is false it says to ignore
the auth header.

Can we maybe take this thread and make it into a wiki page on
http://wiki.freeswitch.org
