Domain Whitelisting

Domain Whitelisting

Domain whitelisting allows access to specific domains by bypassing network restrictions. Instead of manually adding individual IP addresses to a firewall, whitelisting a domain grants access to all associated IPs dynamically. This is especially useful for calls and meetings, ensuring uninterrupted connectivity without frequent firewall updates.
Once the media domain is whitelisted or if no firewall is configured in the network, the admin must run an access test to confirm that the status is set to "Allowed."
Info
Domains and ports to whitelist in the firewall
Domain: mediaserver.zohortcplatform.com
Port range that must be allowed for the domain:
  1. 3479-3481 (UDP)
  2. 443 (TCP/TLS)
How admins can run the accessibility test:
  1. Navigate to the admin panel by clicking on your profile picture.
  2. Under Organization, select Media Domain Access.

  3. Click the Run access test button. You will find a network confirmation alert.
  1. Click Run to proceed with the test.
  2. You will see a list displaying domain name, port range, and their respective statuses: Allowed or Blocked.
Note:
  • If any of the domains are Blocked, the admin should whitelist them in the firewall. Afterwards, rerun the accessibility test until no domains are blocked.
  • Refer to the following doc  to learn how users can check blocked domains and share the report across the organization.
