I am using Cisco Firepower 2100 series firewalls. Whole network has lots of Video conferencing devices.
VC devices are mainly Cisco SX-80
There's a huge delay,break,jitter for VC when using Cisco firepower. Once the devices are detached from firepower and connected straight there's no issues.
I have not enabled any IPS, any port blocking in Firewall. Anyone, any idea why is firepower causing disturbance to the video conferencing.
Try disabling inspection for RTSP from global_policy
From FTD Cli enter below command
> configure inspection rtsp disable
Hope This Helps
