Manually downloading TLS certificates for SIP-based devices

Last Updated:

Zoom periodically updates the certificates required for Conference Room Connector devices to join a Zoom meeting with a TLS connection, BYOC (Bring your own carrier), and devices utilizing SIP-connected audio. When these certificates are updated, administrators may need to install the new certificates to continue connecting to Zoom meetings.

Note: Zoom is rotating it's certificates, and organizations will need to ensure their SIP-based devices are utilizing the following certificates for Zoom Meetings by January 1, 2024.
