Zoom Phone certified devices decertification
Zoom periodically reviews Zoom Phone certified devices to confirm whether they continue to meet current security, technical, provisioning, firmware, and feature requirements. When a device no longer meets these requirements, Zoom may decertify it. This article explains what decertification means, how Zoom communicates it, and what steps you should take to avoid service disruption.
For a list of currently certified devices, see Zoom Phone Certified Hardware.
Why a device may be decertified
Zoom may decertify a device if it no longer satisfies one or more of the following requirements:
- Current security standards
- Supported cipher suites
- Firmware capabilities
- Hardware specifications
- Vendor support availability
- Current or future Zoom Phone functionality
Note: Device decertification is separate from any end-of-sale or end-of-support process announced by the device manufacturer.
What happens when a device is decertified
When Zoom identifies a device for decertification, Zoom may take one or more of the following actions depending on the severity of the issue and technical feasibility:
- Send advance notice to affected account owners and admins
- Publish or update a support article listing affected device models and relevant dates
- Include the decertification in Zoom Phone release notes or preview communications
- Prevent affected devices from being newly added to Zoom Phone through manual provisioning, bulk upload, or application programming interfaces (APIs)
- Limit or stop automated provisioning updates for affected devices
- Limit or stop firmware updates made available through Zoom
- Provide best-effort support for issues that can't be resolved on the affected device
- Allow continued calling functionality where technically feasible
How decertification affects your devices
After the decertification date, affected devices may still be able to place and receive calls where technically feasible. However, you should expect the following limitations:
- Automated provisioning updates may no longer be delivered
- Firmware updates through Zoom may no longer be available
- Configuration changes may not be applied
- Full technical support may no longer be available
Note: If a decertified device is reset, experiences a technical issue, or needs to be re-provisioned, it may not be able to reconnect to Zoom Phone.
How to prepare for device decertification
To avoid service disruption or reduced functionality, review your devices and transition to compatible models before the decertification date.
- Review the list of affected device models published in the relevant support article or Zoom Phone release notes.
- Identify which of your devices are affected.
- Evaluate replacement options. Where available, Zoom will provide links to manufacturer information, replacement guidance, or available manufacturer programs.
- Provision compatible replacement devices before the decertification date.
Note: Replacing affected devices before the decertification date helps ensure uninterrupted calling and provisioning for your users.
