We have about 10 sites with varying bandwidth. Most about are around 10 Mbps and the other two 100 Mbps. We frequently receive freezing between one of our 10 Mbps and 100 Mbps sites. The site with 10 Mbps frequently overdrives their internet so we feel that is the real issue. We do not receive any error codes or system resets anymore, just frozen video. Audio will continue to work. Our sites are connected via Site-to-Site VPNs and since we are using cloud, QoS will not help if the problem is bandwidth. Is there anything that can be tweaked to prevent the video from freezing?
