Dear Team,
Am facing an issue with my IP Phone 8841, the phone not booting up and its shows red light on the mute button.
I have recently two phone under smartnet with similar problem, can anyone advise what could be the reason to occur this boot issue. All the reported phones are connected on the same switch and same CUCM.
Appreciate your kind advise.

Hi,
If phone not booting up and stuck on upgrading or blank screen and the speaker/Mute/line button flashing constantly red colour max of the time issue suspected on hardware.
In this case phone having bootstrap loader issue which means phone unable to download firmware which stored on flash memory of IP Phone for initialising hardware and software of ip phone.
So raise RMA for this phone as already suggested by @Nithin Eluvathingal if you have valid contract with Cisco.

Most probably it could be a device issue. If you have a valid smart i would suggest to raise RMA you get it by NBD. if its a new delivery less than 90 days, you can even Claim DOA.
