*odd one* 20 second delay on the park hints

this is a strange one, looking for some help.
using snom phones with park obits lighting the LEDS when a call is parked. There is about a 20 second delay before the LED turns on and I can’t figure where this delay is coming from.
I can park a call then use core show hints and it will say 71 is idle. About the 4th time I run that command it will turn to inuse and the LED will turn on. Same thing happens when that call is taken off park, it takes about 20 seconds for the LED to turn off.

I tried lowering the registration times on the phones and it made no difference.

Is there some type of timer for these hints that refreshes before the hint actually works?
