SOLVED Authorization challenge

[Andrew Byrd]

I noticed my parking lot lights are intermittent. Sometimes they are green, sometimes orange and other times they are green but do not turn red when I park a call. I went to the logs and see this: Is this affecting the issues and if so what would I do to correct

Just to note: I can factory reset the yealink T29G, then reprovision it and the lights work correctly. When parked the green turns to red. But after a few minutes it stays green and never gives a red blf again, although it does park the call correctly

In my mind the problem is solved. Just to recap what the problem was:

1) I have a Yealink T29G
2) I reboot it and the parking lot light works fine. It goes solid red when a call is parked. I would rather it blink but solid red atleast tells the other parties in the office which line is parked
3) After about 1 minute, the call park button still works, but it stays green, thus, no one knows which line is parked

Solution:

Changed transport from TCP to UDP. Problem fixed

I am sure there are other ways to fix this issues but this fix worked.
