I am using polycom realpresence 500 device and on firewall it's natted with a public IP. When I am initiating a call using realpresence mobile app or realpresence desktop to realpresence 500 device using public IP call is conneting but there is no audio and video and in statistics it's showing packet loss. But when I am connecting call using local IP between realpresence mobile or realpresence desktop to realpresence 500 it's working fine and there is no issue also there are no packet loss.
Cann anyone help me in this issue? I am attaching screenshots for you reference.
you checked the FAQ about Firewallsettings?
In short Admin Settings > IP Network > Firewall
Check in "Fixed Ports" and open the ports you see in GUI on your firewall, plus port 1720. Also forward them to your GS500. NAT Config = auto, if it doesn´t work fill in manually.
What about firewall support for IP Inspection, where the packets are inspected for imbedded IP addresses that need to be NAT'ed?
