[asterisk-users] How to execute priorities following a caller hangup in a successful Dial?

Keep it as simple as you can.

[test]
exten => 12345678900,1,Noop(#### Set callER hangup handler
CHANNEL(name)='${CHANNEL(name)}' SIPCALLID='${SIPCALLID}')
 same => n,Set(CHANNEL(hangup_handler_push)=test_caller_hangup,${EXTEN},1)
 same =>
n,Dial(SIP/pbx-nyigc/4408,60,gb(test_pre_dial^${EXTEN}^1)F(test_intercept_callee,${EXTEN},1))
 same => n,Noop(### Running post Dial() dialplan on callER
CHANNEL(name)='${CHANNEL(name)}' SIPCALLID='${SIPCALLID}')
 same => n,Gosub(test_intercept_caller,${EXTEN},1)
 same => n,Hangup

[test_pre_dial]
exten => _X.,1,Noop(#### Set callEE hangup handler
CHANNEL(name)='${CHANNEL(name)}' SIPCALLID='${SIPCALLID}')
 same => n,Set(CHANNEL(hangup_handler_push)=test_callee_hangup,${EXTEN},1)
 same => n,Dumpchan
 same => n,Return

[test_caller_hangup]
exten => _X.,1,Noop(#### Running callER hangup handler
CHANNEL(name)='${CHANNEL(name)}' SIPCALLID='${SIPCALLID}')
 same => n,Dumpchan
 same => n,Return

[test_callee_hangup]
exten => _X.,1,Noop(#### Running callEE hangup handler
CHANNEL(name)='${CHANNEL(name)}' SIPCALLID='${SIPCALLID}')
 same => n,Dumpchan
 same => n,Return

[test_intercept_callee]
exten => _X.,1,Noop(### Running post Dial() dialplan on callEE
CHANNEL(name)='${CHANNEL(name)}' SIPCALLID='${SIPCALLID}')
 same => n,Dumpchan
 same => n,ExecIf($["${DIALSTATUS}" == "ANSWER"]?Hangup)
 same => n,ExecIf($["${DIALSTATUS}" == "BUSY"]?Busy)
 same => n,Hangup

[test_intercept_caller]
exten => _X.,1,Noop(### Running post Dial() dialplan on callER
CHANNEL(name)='${CHANNEL(name)}' SIPCALLID='${SIPCALLID}')
 same => n,Dumpchan
 same => n,Hangup
