DigiCert Global Root G2 Transition Maintenance Notice for hardware phones including generic devices (United States)
Scheduled for Apr 19, 17:00 - 21:00 PDT
Zoom will perform service maintenance in the following SIP zones to replace certificates used by hardware phone (including supported managed and generic non-Zoom-managed devices) with certificates that will be signed by DigiCert Global Root G2 certificate authority. Action is requested for non-Zoom-managed "other" devices. There is no action required for supported managed devices, since it already has the DigiCert Global Root G2 pushed from Zoom.

US West (N.California, N.California 2, N.California 3, N.California 4, N.California 5, N.California 6)
US East (New York 2)

Zoom will be transitioning to certificates signed by DigiCert Global Root G2 certificate authority on our infrastructure during this maintenance window, and this will be a permanent change. We will not be able to postpone the date any further.

Customers are requested to keep both DigiCert Global Root CA and DigiCert Global Root G2 installed on their generic non-zoom-managed devices as we work through this transition.

If you have not done so, install DigiCert Global Root G2 root certificate on your generic devices. You can download G2 certificate here: https://support.zoom.com/hc/en/article?id=zm_kb&sysparm_article=KB0061202

During the maintenance window, a brief disconnection of calls may be experienced while the TLS connections are being reset. Once the TLS connections are reset, the devices will attempt to use Zoom’s new certificate that is signed by DigiCert Global Root G2 certificates. Customers are requested to test inbound and outbound calling for generic non-Zoom-managed devices to ensure that the services are functional after the certificate updates.
