STUN server address: stun.ezytel.net.au
A STUN server is normally used if you're experiencing call problems such as "one way" audio, where you might hear the caller, but they can't hear you, or vice versa. This is normally caused by a Network Address Translation (NAT) problem in your local network, and the use of our STUN server will help overcome the issue.
In simple terms, a STUN server assists your extension's handset find and know it's external IP address, so that the correct traversal of audio can be completed between both parties in a call.
Enabling the use STUN depends on the type of handset you're using.
