Yealink MP Phones no DHCP or Network Access with static

[wesleybauman]

Hello,
I've using Yealink MP5X phones for nearly a year and they have had their own slew of issues but otherwise functional. However, today hit the 30 day threshold to start pushing out Firmware to the phones and most of our devices pulled it overnight to the 122.15.0.142 firmware. And now, almost of them have been reported as down or unable to make/receive calls. I have a device on my desk here and setting static IP information, the device never comes online. I can't get to the web interface HTTP or HTTPS, and I can't even ping the device even after confirming the configuration is correct.

Anyone else running into this issue? I've submitted a case with both MS and Yealink to see if anything is known or if I can get rollback steps.
