## Enable Conference Call Settings

Select whether to enable or disable 1:1 calls and group calls, whether students and teachers can use their webcams, and whether calls can be recorded with student consent during classroom sessions.

## Update Firewall and Content Filter Settings

GoGuardian products require open connections to a number of back-end services. Firewalls and other content filters may unintentionally flag and block connections to these services due to the elevated number of active connections or HTTP requests.

If you're experiencing large-scale connection issues, check your firewall or any additional content filters for blocked connection attempts to the services listed below. If connections are being blocked, add the corresponding URL to your firewall or filter's allowed list.

GoGuardian Teacher's Video Conferencing features connect to the following services.
