[VoIP] Additional Asterisk Features

[Mark Rudholm]

If you set the zap channel's "immediate" variable to "yes" the "s"
extension in the context to which the channel is assigned will be
executed immediately.  There's no need to name the context anything
in particular.  There's also no need to limit the context to
ringdown service (although it's a good idea).

Here's my "front_door" context:

[front_door]
exten => s,1,System(/usr/bin/wget -q -b -o /dev/null -O /dev/null http://127.0.0.1:9000/"status.txt?p0=display&p1=Doorbell&p2=Doorbell&p3=20&player=*")	; Announce via Squeezeboxes
exten => s,n,SetVar(_ALERT_INFO=Bellcore-r3)            ; Ring Cadence #3 is three quick rings
exten => s,n,Dial(${kitchen}r3&${bedroom}r3&${garage}&${living_room}&${office}&${work}&LOCAL/500 at front_door&LOCAL/600 at front_door,42)
exten => s,n,Playback(were-sorry)
exten => s,n,Playback(vm-nobodyavail)
exten => s,n,Hangup()
exten => 500,1,Set(CALLERID(all)="Front Door"<2138531212>)      ; set CID to something Teliax will accept
exten => 500,n,Dial(${cellphone})
exten => 600,1,SetVar(_ALERT_INFO=Bellcore-r5)          ; Bellcore-r5 is defined as silent in my ATAs
exten => 600,n,Dial(${guest_room})
