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.
