BLF Light stuck on busy for select users

[papergavin]

Hi Folks,

I deployed about 17 voip phones for a company. All provisioned and set up the same. There is about 4/5 users whos blf light is always busy even if they aren't on a call. They can still receive transfers/calls, but the users are never truly sure if they are on the phone or not.

I tried to factory reset them, but they all just immediately went back to "busy".
