Yealink YMCS RPS Older model phones NOT showing 10/20/2025 SR
Modified on Mon, Oct 20, 2025 at 1:03 PM
Introduction
To enhance the security of RPS service for legacy devices, Yealink will no longer provide RPS support for certain older devices. To continue using the RPS service, these devices must be upgraded to the specified firmware version and used in conjunction with the RPS PIN feature.
(For unsupported versions and recommended upgrade versions, please refer to: https://support.yealink.com/en/portal/knowledge/show?id=687f7b3706b3cf2066d84dea)
Procedure
- You can view the RPS PIN associated with each MAC in the platform's RPS device list. Please provide the corresponding RPS PIN to your end customers so they can enter it on their devices to complete the RPS process.
(1) For devices upgraded to the recommended firmware version, the RPS PIN only needs to be entered once. Future access to RPS will not require re-entry.
(2) For devices already upgraded to a supported version but not the recommended version, RPS access is allowed via PIN entry; however, the PIN must be re-entered each time RPS is triggered.
NOTE
If the platform does not display an RPS PIN for a device, it means the device has a built-in authentication mechanism, and no manual PIN entry is required.
- When the RPS service is triggered on the device side, a prompt will appear on the screen. The user can then enter the RPS PIN obtained from the platform to complete the RPS process.
NOTE
If the PIN is entered incorrectly 5 times, the device will skip the RPS process.
Dear Customer,
Due to historical reasons, an old RPS service has been maintained exclusively for certain End-of-Sale (EOS) or End-of-Life (EOL) Yealink devices and specific customers.
Since the launch of our new RPS server in 2020, the service has been operating reliably and securely. To provide our customers with a more secure and reliable RPS service, we will officially discontinue the old RPS server as of October 1, 2025.
Devices running firmware versions lower than those listed in the "Affected Versions" table must be upgraded to the corresponding "Recommended Versions" to connect to the new RPS server. We strongly recommend completing the firmware upgrade before September 30, 2025, to ensure uninterrupted and stable redirection services.
To minimize the risk during upgrade, we recommend performing the upgrade within the same major version branch (the second digit in the version number, e.g., xx.84.xx.xx).
Please note that certain EOL models, will no longer support RPS service access.

The new RPS server introduces enhanced security mechanisms, including additional verification processes. After the firmware upgrade, some devices may prompt users to enter an RPS PIN upon first-time connection to the new RPS server. Once the verification is complete, the RPS service will function as expected.
