We have a request form a number of our customers who use BLFs to display parking lot lines. They wish to have an audible "chirp" from the speaker of the phone when idle, if there are parked calls. So - a setting "audible BLF" with either a simple enable/disable or perhaps several sounds to choose from would help.
It would chirp only when the phone is idle and a BLF was "active"
