I have been having issues with multiple yealink T-29G bricking on a reboot. The red light will be solid on the top right and the screen will be black. The phone itself is unresponsive. Has anyone else had issues similar to this? We have noticed there is a similar MAC Address range for the issue, the first three octets being 80:5E:C0.

Thank you.

Try using a power brick. Could be the POE router

Newsflash: They ALL start with the same 6 characters. That's the manufacturer ID. All of my Yealink family phones start with that, even the 27's and 46s.(*)

There was a bad batch of phones made. I'm not sure when, but I had one failure out of about 20 sets purchased between April and August. A call to my vendor got an RMA.

(*) To be fair, not ALL Yealink phones start with the same 6. Earlier series, like my T28P phones start with 00:15:65
