[Asterisk-Users] Can Asterisk work in a proxy setting- a challenge

[Steve Jones]

First of all, I assume that since you're asking the question, you want to trunk, or send/receive calls that are on the OTHER SIDE of a proxy from you.  Certainly asterisk, as a PBX, can service local IP phones, and connect to PSTN lines, without regard to ANY internet connection.

Proxy servers are application based, so the proxy has to understand and process each application specifically.   

"Proxy" is generally used to describe a web (http) proxy, but it could be any application (ftp, telnet, etc).   There are proxy plug-ins for applications, but those are going to be specific to the application, and the specific proxy program you're using, so the proper thing for you to do would be to first decide what you want to put THROUGH the proxy (H323/SIP/IAX2, etc) and then see if your proxy vendor has a module that'll support that protocol.  

I don't have any experience trying to do this, but my gut feeling is that it's not going to be feasible - Not because it's technically impossible or anything (although it may be - I'm not an expert in writing proxy plugins), but specifically because there's most certainly going to be some overhead, delay, buffering, etc in the proxy, and it's going to be technically impractical to do high-quality VoIP..  I could be proven wrong though - I think there are H323 modules for some proxy systems.
