Yet WinStun reports:
Nat with Independend Mapping and Port Dependent Filter - VoIP will work with STUN
Does not preserve port number
Does not supports hairpin of media
Public IP address: xxx.xxx.xxx.xxx <---- changed by me.


I have ports 3478-3479 open on the firewall for Stun.
This is currently BETA ver. 3.1 but it has never worked with any version.

Using stun.3cx.com and stunserver.org

Have you opened port 5060 for outbound?

Please try the trace route for the stun server. To see it can be reach or not from your ISP.

If cannot try the other public stun server:
stun.voipcheap.com
stun.fwdnet.net

My ISP unable to reach the stun server of stun.3cx.com. My trace route log as below:

5qg4 Try this one:

stun.fwdnet.net

Should work,

Best to do a search in your country for STUN servers, in general you will find a few public ones. No need to be bound to the stun.3cx.com

My philosophy is that you make most calls in your country of origin so might aswell use a stun server in that area, shorter pops and routes means less latency.

and yes the stun.3cx.com times out again it is a rouer issue on cw.net not so much the 3cx.com network it is a gateway before that.

Hi itfarmer,

Thanks. In my country stun.3cx.com always time out. I am now using stun.fwdnet.com for PBX and stun.voipcheap.com for remote test. Both are OK in asia.

Problem solved. My Sonicwall Intrusion Prevention Service was the culprit in the "Stun not resolving external IP" problem. Turned it off and it works great.
