We are using OCS 2007 Standard and we are experiencing video freezing issues for remote users. Our remote users have a device established VPN between the site and the OCS A/V server, no port filtering is in place between this connection.
After establishing a video session the video works for about 1-2 minutes. After that the video freezes and the only way we are able to un-freeze the video is to cancel the session and restart video.
We are using Logitech Orbit webcams. Any video session on the LAN works fine with these webcams.
What can I do to troubleshooting this issue?
