Notes for features with partial support

Admin password

The Admin Password setting located in the account-level desk phone settings doesn't apply to these models:

  • AudioCodes: 445HD, 450HD, C450HD

Note: The Yealink CP925 doesn't support admin passwords more than 8 characters in length. Make sure to set an admin password that is 8 characters or shorter for it to apply to the CP925.

Assisted provisioning

Algo: Assisted Provisioning is available for Algo Paging Devices. As of the time of this release, certain device such as model 8180 do not pass the Assisted Provisioning, therefore the model 8180 device may need to be manually provisioned as “Other/Generic” device while we are working on resolving the issue.

Cyberdata: Assisted Provisioning is available for Cyberdata Paging Devices. However some older product lines are missing the necessary SSL device certificate support required for Assisted Provisioning (aka Auto-URL Provisioning), therefore the older product lines may still need to be manually provisioned as “Other/Generic” devices. Please reach out to Cyberdata support for details.

Do not disturb (DND) status

The DND status only applies to the phone you set it on. This status does not sync on other desk phones assigned to you or the Zoom desktop client or mobile app.

  • Yealink: All on-screen and sound notifications are blocked.
