Went by new customer- going back tomorrow for P.A. etc...and on initial visit noticed all the programmed DSS buttons are flashing on all phones....
Any idea what may be causing this? Will be tinkering with tomorrow but figured if a "light bulb" goes off with anybody here for cause that would save some time.
Confirmed buttons are programmed correctly and do function properly as DSS buttons - extension calling.

KX-TA824 with 77xx series phones and TVA50 VM.
