New Revision: 54173
URL: http://svn.digium.com/view/asterisk?view=rev&rev=54173
Log:
The best time to get your feature request fulfilled is when you catch a
developer on IRC in the middle of the night that can't sleep. :)
This introduces a new dialplan function, DEVSTATE, which allows you to do some
pretty cool things.
First, you can get the device state of anything in the dialplan:
NoOp(SIP/mypeer has state ${DEVSTATE(SIP/mypeer)})
NoOp(The conference room 1234 has state ${DEVSTATE(MeetMe:1234)})
Most importantly, this allows you to create custom device state so you can
control blinky lights directly from the dialplan.
Set(DEVSTATE(Custom:mycustomlamp)=BUSY)
...
exten => mycustomlamp,hint,Custom:mycustomlamp
