[asterisk-users] Possible to light up a LED on Snom phones?

[Norbert Zawodsky]

Hi everybody!

I've setup my dialplan so that if an extension dials *21*, that
extension is added/removed as a queue member to a queue. (State toggled).

But it would be great to get an "optical feedback" of that phone's state
regarding the queue membership.

Does someone know if it is possible to light up a LED under this szenario?

Many thanks!
Norbert
