RE: Default password resets itself

I have a question.
I have some SIP phones, most of them T33G and T48U.
It happens, I haven't managed to understand how and why, the admin password is resetting back to default itself, every now and then.
I didn't track specific time schedules or specific devices.
Not happened to all devices, not happening every 2 days or every week..but is happening constantly.

Can anyone give me any advice?

Thank you!


Will only the admin password be reset, or will multiple settings be reset as well?
E.g. the user password, the phone is reset to factory settings, account settings?

Are the telephones in question supplied with power via PoE?
If so, try powering them with a separate power supply.

Kind regards,

I am not an employee of Yealink.
Dutch is my native language, not English. Apologies for my imperfect grammar.
Please do not send unsolicited PM messages. I will not answer them.
