Network Firewall Settings for CRC and Enhanced API Connector

H.323 and SIP endpoints require the Internet access described in this article to access to Zoom meetings and webinars. The Zoom Enhanced API Connector, if deployed in your environment, also requires Internet access to function. The tables describe the protocols, destination ports and destination IP addresses used to communicate with Zoom cloud services. Your firewall should be configured to allow established, related return connections from Zoom's cloud to your H.323 and SIP endpoints, and the Enhanced API Connector (if deployed).

This article covers:

H.323 endpoint access to Zoom Cloud Room Connector
SIP endpoint access to Zoom Cloud Room Connector
Enhanced API Connector access to Zoom Cloud Services
Firewall rules for other services
