I know how MWI and BLF works, that's not my question. I'm talking about 
lighting up lights on the phone on other occasions, not related to MWI 
or BLF. Check the examples I gave again.

Can Asterisk (through SIP or maybe another protocol) "control" lights on 
an IP-phone like Snom, Yealink or other ?

Also : can we control SIP notify or SIP option packets inside the dialplan ?



Kind regards,
Jonas.
