DoS & spoof protection and VoIP
Unstable VoIP connection if DoS settings for UDP rate are applied.
UDP flood settings cause VoIP traffic to drop.
- Go to Intrusion prevention > DoS & spoof protection.
- Under DoS settings, clear the Apply flag checkboxes for UDP flood.
- Test the VoIP connection.
If this setting resolves the VoIP issue, lower the UDP flood protection values before applying the flag again.
A single value doesn't work for all environments. Adjust the values until you find those that work best for your VoIP setup.
