End-of-sale Polycom models that were manufactured before certain dates are not supported by Zoom Phone. They do not contain the factory-installed certificate, causing the device to fail the certificate authentication that leads to registration failure. Learn more on the Polycom website.
Note: Zoom only works with Polycom devices that are running at least version 4.0.0 of the UCS firmware. In previous versions (Polycom SIP software 3.x or earlier), upgrading from the phone's web interface, registration, and provisioning will not work with Zoom. This restriction does not apply to OBi ATAs.
