X-Lite 4 Setup Success

[claganga]

All stun does is help the softphone see what's the ip address and how the router NATting effects ports. So your soft phone on the laptop with out stun thinks it's ipaddress is your internal address ie (192.168.1.x) but with stun it see it's your actual public ip address. This is simplified but you get the point.

The audio quality is unaffected by stun. what is the audio quality problem's you are having?

I've always understood that STUN doesn't affect audio quality, but the audio was really choppy when I included the STUN server (zeus.voipwelcome.com) in the configuration settings. By comparison, I didn't have these audio problems when using a SIP app on my iOS device which is not configured to use STUN.

At any rate, I was able to search these forums and the forums at broadbandreports to finally figure out the correct settings without having to use STUN. In summary, I added ":5061" to the end of the domain name ("sip.voipwelcome.com:5061") and, in the Topology section, I set the Firewall Transversal Method to "Auto-detect (ICE, recommended)".

Now X-Lite works great and I don't notice the choppy audio that I was experiencing when I had it configured to use STUN.

For all my fellow Mac users, I also wanted to mention that the simplicity of the "Google Telephone" app makes it a pretty stellar softphone application:

Google Telephone has fewer features that X-Lite, of course, but its simplicity and ease of use gets a lot of points in my book.
