<br>
is there some way to make Asterisk light up a certain light on an IP-phone ?<br>
<br>
Like MWI, the message waiting indicator can light up if there is voicemail.<br>
<br>
Could this light, or even other lights (like BLF-buttons) be used to give a
visual notification to the user ?<br>
<br>
For example : if a certain value is set in the Mysql-DB and Asterisk reads out
this value, can Asterisk react upon it inside the dialplan to make a light lit
up ?<br>
<br>
2nd example : if a certain extension is called, can we perform inside the
dialplan an action that makes a light lit up on a Snom or Yealink IP-phone ?<br>
<br>
I don't know if all this is at all possible, but it doesn't harm asking I
guess...<br>
<br>
If BLF works, then maybe more things are possible in the same way. Just
thinking outside the box here.<br>
<br>
<br>
Kind regards,<br>
Jonas.<o:p></o:p></span></font></p>

font-style:italic'>The answer is highly dependent on flavor of Asterisk and
phone. In my experience, Asterisk can generally only light up the MWI light on
any applicable phone. I have Polycom 501 phones and I can make MWI light up by
leaving a message for that phone or my generic extension 108. If I zap the
message, the light goes off. So in either of your examples, I could call an
AGI to turn the light on or off. As I read, SNOM are pretty much equivalent to
Polycoms regarding MWI functionality, don’t know about Yealink.</span></font></i></b><font
