T28P is an old yealink phone model, which has limited memory, and already EOL.

For the issue you met, suggest you to do the factory reset(long press the OK key for 5s), but before you do this, please export the config.bin file first, after you resetting the phone, export the config.bin file back to phone, the setting will remain the same.

For how to export the config.bin file, please refer below FAQ:

Any question, please feel free to let me know.


Hi Travis

Thank you for coming back to me about this issue. I didnt actually know this phone was no longer supported by Yealink when I brought it. They still retail for about £150.00 which is quite alot and I managed to pick up 6x of them for about £85.00 each.

I think the phones are excellent quality and am more than happy with them. Much better than the cisco/linksys I have used in the past. I'm really surprised they have just stopped support like that. What if new bugs are discovered in the future, especially around hacking and phone fraud? Quite surprising really.

Anyway, I have taken on the advice you have said. Do you know if this will actually work though?

The reason I asked is because before I came to post on this forum, I did spend a good amount of time searching on here and on google. There have been people who have said they have tried resetting the firmware and they were still unable to clear the ringtone memory from the phone.

Is resetting the phone different to re-flashing the firmware. And do you know if this will work or is this just something you would recommend me to try at this stage???

Thanks for the help again

Hi Tony,

I think there might some misunderstanding.

T28P is end of line, that means we don't produce it anymore, but our support will continue, please don't worry about it.

To reset the phone is what I recomand you to have a try, but I think it should be the memory reason, reset the phone will clear the memory.

Any update, freely to let me know.
