[Asterisk-Users] SIP and firewalls?

[Hagen Rode]

Hi 

We are currently using Asterisk 1.2.4 with IAX and app_meetme for
conferencing, but are looking to move to SIP because of issues with an IAX
control we're using. 

The reason we moved from SIP to IAX in the first place was because of the
poor NAT traversal with SIP. At that stage we were using Asterisk 1.0.*. How
does Asterisk 1.2.4 handle NAT traversal and firewalls compared to the older
Asterisk? Have there been improvements? Or is SIP (obviously depending on
what client you use) still poor when it comes to NAT traversal and
firewalling? 

Many thanks

Hagen
