I am experimenting with the BLFs and trying to reverse the behavior of one of them. Currently, I have a BLF that allows me to call a colleague and shows the status of the colleague on his phone through the LED. By default, the LED lights up when the colleague is absent (DND is on) and turns off when the colleague is online (e.g., DND is not active). I want to change it so that the LED lights up when the colleague is online / DND is not active (which would be more logical since the LED is green).
We both have a snom D710 and are using freepbx.
How can I achieve this? Any help would be greatly appreciated.
The behavior of the phone itself (color of/state of the BLF light) is controlled by the phone itself. The hint that Asterisk generates tells the phone what type of state the remote phone is in (idle, busy, ringing, etc.) and the phone with the BLF key monitoring that hint then has a preprogrammed behavior. I have never worked with Snom phones so I can’t speak intelligently about their abilities and behaviors, but most sip phone manufacturers don’t let you change BLF behavior in their firmware. The only one I know of off hand that will are Fanvil Phones. I think Yealink may let you make a couple of changes around the behavior, but I can’t remember.
