I have four BLFs configured to be parking spots on Yealink T38G phones. I would like them to blink when a call is parked on any of them. Parking is working great, but the multiple receptionists in this setting can’t tell which parked call has been picked up and which is still waiting. It would be ideal if the BLFs would blink while a call is parked, and then go back to static red when the call is picked up. Can someone help me with this?
