[Freeswitch-users] DND emulate key system

[Kevin Wormington]

Hi,

I am wanting to emulate key system behavior of having a BLF key indicate 
when an extension is on DND.  I realize this is not strictly what BLF 
is.  I'm assuming that the DND keys of the phones (yealink) would have 
to be programmed to send * codes for DND on/off that would call dialplan 
entries to set presence along with some component to fire the event for 
the presence message so phones with the BLF keys would all get updated. 
  Before I dig into this under the hood I wanted to ask if others had 
already done this?

Thanks,

Kevin
