[OpenSIPS-Users] OpenSIPS as the Firewall

[duane.larson at gmail.com]

Are your diagrams the path that SIP takes or RTP? Asterisk can be internal  
and private from the outside world when it comes to SIP. It can also be  
internal only when it comes to RTP but you would need to use a relay server  
like Mediaproxy or RTPProxy. Mediaproxy can sit on the internet with a  
public IP and Asterisk can be behind a firewall.
