Notes for features with partial support

Admin password

The firmware requirements of AudioCodes 445HD, 450HD, C450HD to support admin password:

  • 445HD, 450HD, C450HD: 3.4.6.565 or later versions

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

  • AudioCodes: MP112, MP114, MP118, MP124
  • Algo SIP-based devices
  • CyberData SIP-based devices

Aim call park (park using line key)

Aim call park (park using line key) is supported on these models:

  • AudioCodes: 445HD, 450HD, C450HD

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 (also known as 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. You can identify if a CyberData device supports assisted provisioning. 

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.
