How to continue processing a context after a Hangup

Asterisk Application ‘System()’ in h extension to

create callfile which will handle your callback.

You can also try for ‘Originate()’ application.

Example:

[Main]

exten => 111,1,Goto(cb,1,1)

exten => 222,1,Dial(SIP/666666)

[cb]

exten => 1,1,NoOp(Incoming call from # ${CALLERID(num)})

exten => 1,n,Goto(callback,333,1)

[callback]

;prepare for callback

exten => 333,1,NoOp(Hangup then callback to cellphone)

exten => 333,2,Hangup

exten => h,1,NoOp(copy callback.call file to /var/spool/asterisk/outgoing)

exten => h,n,System(echo -e "Channel: SIP/${CALLERID(num)}\\nContext: Main\\nExtension: 222" > /tmp/${UNIQUEID}.call)

exten => h,n,System(/bin/sleep 10s)

exten => h,n,System(mv /tmp/${UNIQUEID}.call /var/spool/asterisk/outgoing/)

OR

exten => 1,1,Wait(2)

exten => 1,n,Set(CID=${CALLERID(num)})

exten => 1,n,NoOp(Call from ${CID})

exten => 1,n,Hangup

exten => h,n,Originate(SIP/1001,app,Dial,SIP/1002)
