TLP Limitations

Yealink has shut down an old RPS service that was exclusively supporting EOL (end of life) devices. In addition most devices now have a minimum firmware version required for touchless provisioning (TLP) to function. If a handset is no longer supported or running an unsupported firmware version it will not be able to be TLP'd and will require the auto provisioning details to be manually entered into the handset if it is factory reset.

NOTE: Unless a handset is factory reset it will continue to function without issue and is not affected by these changes.

There is no alternate solution that enables TLP functionality on unsupported devices.
