[asterisk-users] Do I need a SIP Proxy for this?

[Alex Balashov]

No, you don't necessarily need a SIP proxy for this.  Furthermore, while 
a SIP proxy might assist with certain SIP-level reachability issues, it 
will do nothing for the actual audio (media) if there are NAT issues 
that prevent that from getting through.

As the other reply said, "this isn't working out well" needs some 
explanation.
