3CX SIP Proxy Manager documentation

[pdq]

Can we standardize the documentation for using the 3CX SIP Proxy Manager at :
http://www.3cx.com/blog/releases/sip-proxy-manager/ ?
Specifically:
1. Can for screenshots of the SIP Proxy Manager show the same IPs and what is up with 0.0.0.0?
2. I see three different WAN IPs and does not follow the parts about Typical Scenario and Assumptions and the discussion below use those IP addresses.

I am attempting to make this work with a Cisco 503G and trying to decrypt which Ip is where is a challenge. Thanks

Hi,

The 0.0.0.0. is the network card that you are going to use as the proxy, for other phones to connect to. I have forwarded your request.

Then is should show the same IP address as the proxy screen shot above it.

0.0.0.0 is not a valid IP
