Zoom Cloud Room Connector (CRC) API integration guide. Enables SIP/H.323 conference room systems
(Cisco, Polycom, etc.) to join Zoom meetings. Covers device registration, dial-in configuration,
port management, and room system integration. Use when connecting traditional video conferencing
systems to Zoom or managing room connector infrastructure.

Zoom Cloud Room Connector (CRC) API

Connect SIP/H.323 conference room systems to Zoom meetings with Cloud Room Connector.

Overview

Cloud Room Connector (CRC) enables traditional video conferencing systems (Cisco, Polycom, etc.) to join Zoom meetings via SIP or H.323 protocols. The API manages CRC configurations, dial-in settings, and room system integrations.

Key Features
