[Asterisk-Users] Help with simple callback application from newbie

[Raf D'Halleweyn (list)]

I use the attached AGI script (place it in your agi-bin directory). It
places a call file in asterisk's outgoing spool directory
(/var/spool/asterisk/outgoing) in my case.

The script is called with as argument the number to call back. Note that
if the call back number is 5 digits or less, it actually calls back the
original channel. That way I can also test the call back from a local
extension. If it is more than 5 digits it always calls back using my
broadvoice SIP account (you should change this).

The call back is initiated from a 'callback' extension in
extensions.conf after you hang up (so it uses DeadAGI). You should make
sure to perform the proper authentication before entering this exension:

[callback]
exten => s,1,Playback(call)
exten => s,2,Playback(ha/back)
exten => s,3,Playback(initiating)
exten => s,4,Wait(10)
exten => s,5,Hangup
exten => h,1,DeadAGI(callback,${CALLERID})

When calling back, the call starts in the 'calledback' extension. It
first announces the call back and then goes to some other extension (in
this case just a DTMF test):

[calledback]
exten => s,1,Wait(1)
exten => s,2,Playback(call)
exten => s,3,Playback(ha/back)
exten => s,4,Goto(testdtmf,s,1)

Improvements that I would like to make, but I don't know how:
-use the dialplan from extensions.conf to make the call back (instead of
always using broadvoice)
-'attended call back', for example when you try to initiate a call back
to a hotel guest.

Good luck,

Raf.
