The table for Zoom Phone rules has been updated to include the use of the UDP protocols for TURN (Traversal Using Relays around NAT) support (UDP 3478). Due to this, we recommend that network administrators, with Zoom-specific firewall or network rules, update their systems. This update is only for the protocol; no changes have been made to the destination addresses used for Zoom Phone. Below are the IP ranges that will be utilized for TURN support (UDP 3478).

Zoom will be making the new Service Provider certificate available on November 5, 2025, ahead of the expiration of the previously issued 2024/2025 certificate on Sunday, December 21, 2025.
No action is required for customers using an identity provider (IDP) or configuration that supports dynamic metadata refresh, as your IDP will automatically download the latest Zoom certificate and rotate it into your account’s configuration starting Wednesday, November 5, 2025.
If automatic update is disabled or your IDP does not support automatic certificate rotation, your organization will need to manually rotate the certificate by December 21, 2025. If the certificate has not been rotated by then, your organization will be unable to utilize SSO services until the certificate has been updated.
