Network Requirements for Enterprise IT

Overview

Converge utilizes Zoom Video SDK for audio/video communications. This document outlines the required network configurations to ensure proper service functionality within your corporate environment.

Quick Implementation Summary

Essential requirements for Converge audio connectivity:

• Outbound TCP ports: 80, 443, 8801, 8802
• Outbound UDP ports: 3478, 3479, 8801-8810
• Domain whitelist: *.zoom.us
• Key IP ranges must be whitelisted (detailed below)

Detailed Network Requirements

Required Ports

TCP:

• 80, 443: Initial connection and signaling
• 8801, 8802: Media transport fallback

UDP:

• 3478, 3479: STUN/TURN services
• 8801-8810: Media transport

Domain Whitelist Requirements

The following domains must be accessible:

• *.zoom.us

Required IP Ranges

IPv4 Ranges (partial list):

• 3.7.35.0/25
• 3.21.137.128/25
• 3.25.41.128/25
• 3.80.20.128/25
• 3.104.34.128/25
• 3.120.121.0/25
• 3.127.194.128/25
• 3.208.72.0/25
• 3.235.71.128/25

IPv6 Ranges:

• 2407:30C0::/32
• 2600:9000:2600::/48
• 2620:123:2000::/40

Proxy Configuration

• HTTPS/SSL proxy servers supported on port 443
• Automatic proxy detection is supported
• Recommended: Allowlist zoom.us and *.zoom.us from proxy inspection

Security Software Considerations

WebRTC Requirements

• WebRTC connections must be allowed
• UDP traffic should not be blocked for optimal performance
• TCP fallback is available if UDP is restricted

Verification Process

To verify proper configuration:

1. Test access to https://zoom.us
2. Verify connection to ports using telnet or similar tools
3. Conduct a test call using Converge platform
