Any call to this will insert into callback_spool
exten => 110,1,DeadAGI(callingcardj.php|5|callback)
exten => 110,n,hangup

then I run
CallBack-Daemon &
10 times

when this perl make Asterisk manager and call
will flow to this context

[a2billing-callback]
exten => _X.,1,Answer
exten => _X.,n,DeadAGI(callingcard.php|4|callback)
exten => _X.,n,hangup


Am I wrong about callback system flow?

thank you.
