Hi All, I cannot get the presence 'Available' to work whilst outside the LAN. I am able to login and make calls without any issues. I have tried with Windows firewall on and off, but it does not make any difference. 3Cx v12.5 on Windows Server 208 R2 SP1. FQDN internal and external resolving correctly. All required ports including 5000 and 5001 TCP are open. Thanks in advance.
