[Asterisk-Users] Dialplan help needed

[snacktime]

What I want is for an incoming call to ring for say 20 seconds, then
hangup, then call an external script.   A simple callback setup.

If I do this,  at priority 3 the caller doesnt' get hungup, but
instead the line just keep ringing after callbback.agi is run.   Why
is that?


exten => xxx,1,Ringing
exten => xxx,2,Wait(10)
exten => xxx,3,Hangup
exten => h,1,DeadAGI(callback.agi)
