Zoom Phone does not support Polycom models which were manufactured before certain dates but were still in production at the time of the end of sale. Since they do not have factory-installed certificates, the devices fail the authentication process of certificates, which causes the devices to fail to register. For more information, visit the Polycom website.
You can use Zoom only if your Polycom device runs UCS firmware version 4.0.0 or higher. Prior versions (Polycom SIP software 3.x and earlier) of Zoom do not support upgrading, registering, or provisioning via the web interface. OBi ATAs are not affected by this restriction.
