Discussion

While ostensibly a SIP ALG is designed to enhance SIP and make the notoriously problematic NAT traversal issues easier to deal with, the simple fact of the matter is that most SIP ALG's are horribly broken. Brian K West has described them as "evil" - which is not really an understatement if you've ever been burned by one.
