Hi Guys, New to the 3CX system, and playing around with it. What I am trying to reach: 3CX running on a VM on MS Azure platform How far am I ? Created the VM, setup the system, installed 3CX and apllied free licence. Created the VoIP provider, registers fine Created some extensions Then in Azure created the following endpoint settings: 5060 -> 5060 5061 -> 5061 5090 -> 5090 TCP and UPD 5000 -> 5000 Now the status is as followed; I can reach the admin web interface from an external IP. Yet, registering a external extension is not possible. Also every single firewall checker run gives me that port forwarding is not properly configured. It probably has something to do with Azure tunneling the traffic, but I can not figure out where it goes wrong. The external IP is 188.8.131.52 and the VM IP is 100.92.142.143. Anyone has an idea what I am missing ? PS Firewall is turned off UPDATE The ports do show up as open when testing with a external website... http://www.yougetsignal.com/tools/open-ports/ Port 5060 is open on suppahost01.cloudapp.net. Yet the soft phone will still not connect. UPDATE 2" Phone connects for a second, and then comes back with error 407... No idea what to do anymore..
