Hello, I´d like to know if I need a SIP proxy to make a call from a soft phone behind a NAT router to other soft phone with a WAN IP.

Hi bitacora,
Thanks for waiting for us to respond to your question.
Yes. You will need a SIP proxy and a media proxy server to allow SIP user agents or desktop SIP phones to communicate when they are deployed in a network environment that involves NAT.
Our Centrex (SIP) proxy and VOIP (RTP) media proxy are designed to do this for you. Take a look here:
Centrex Proxy Server:

Repost as needed,
