[asterisk-users] How to hangup a channel immediately so that it doesn't get charged on cell phone

[Zeeshan Zakaria]

Hi,

On my call back system, I have the  script as follows:

[calback]
exten => s,1,NoOp(* STARTING CALLCHEAP\'S CALLBACK SYSTEM *)
exten => s,n,Set(CALL=${CALLERID(number)})
exten => s,n,Set(DESTINATION=myCallback.2000.1)
exten => s,n,Set(SLEEP=5)
exten => s,n,System(/var/lib/asterisk/bin/callback ${CALL} ${DESTINATION}
${SLEEP} &)
exten => s,n,Hangup

The idea behind this system is that the script picks up the call, notes down
the caller's number, and hangs it immediately. Then the caller gets a call
back.

But what is happening is that cell phone callers are still being charged for
calling into this callback context.

How can I avoid this? I want cell phone users to not get charged for the
call back.
