After reading this guide, you can configure your firewall to allow all required traffic for Prepared Assist and Prepared Live, ensuring full functionality for real-time media, location, and platform access.

Prepared Assist and Prepared Live rely on cloud-based services that require specific domains, ports, and protocols to be accessible.

If your dispatch center uses a firewall, proxy, or network security controls, you must allow outbound access to the domains listed below. Failure to do so may disrupt real-time features such as live video, audio, and location sharing.

• IT Admin or Network Administrator access

• Ability to modify firewall, proxy, or network security rules

Your network must allow outbound traffic to the following domains and ports.

These services support real-time media (audio, video, and location) using WebRTC.

maps.gstatic.com (443)  
fonts.googleapis.com (443)

If your firewall filters by protocol:

• Prepared uses WebRTC for real-time communication

• WebRTC relies on:

  • UDP (3478) for media transport

  • DTLS for secure media encryption

  • TCP (443) as a fallback

Blocking UDP may result in degraded or failed media sessions.

• Regularly test:

  • Live video and audio

  • Location sharing

  • Streaming functionality

• Document all firewall and network changes

• Review Prepared release notes for new domains or updates
