<para>Fixes broken VIA headers on incoming SIP requests
(inspired by Ralph Babel, see http://babel.de/art20080317a.html
for more info). Can be applied if you have remote UAs calling you
from the Internet and those UAs do have crappy Via headers (like
private IPs because there is some NAT involved on their side).</para>
