Hi I was wondering if anyone else was experiencing this. I get this message every few seconds in my log. 11:25:26.921 StunClient:nTestTout [CM506004]: STUN request to STUN server 220.127.116.11 has timed out; used Transport: 192.168.240.61:5060 I'm using using version 3CX Phone System Version5.0.3752.0 and since I don't need STUN (because my users are on the same LAN, and I'm physically connect to my VOIP Provider) because I don't use NAT. What I did in the General Settings, STUN server settings section was to put in a bogus FQDN for the STUN server address. So I'm not sure why the 3CX is sending STUN requests to STUN server at address 18.104.22.168 Any ideas?
