[asterisk-users] Explain HangupCauseClear() and HANGUPCAUSE_KEYS behaviour

[Olivier]

Hello,

I'm giving HangupCauseClear() a try on a Debian Stretch / Asterisk 13.18.3
stack.

My dialplan is:

exten = 1234,1,Set(CHANNEL(hangup-handler-push)=myhandler,s,1)
same = n,Dial(SIP/foo/1234)
same = n,Gosub(myhandler,s,1)
same = n,HangupCauseClear()
same = n,Dial(SIP/bar/1234)

[myhandler]
exten = s,1,Set(HKEYS=${HANGUPCAUSE_KEYS()})
...

foo trunk is configured to reject calls.
bar trunk is configured toaccept calls.


I would expect ${HANGUPCAUSE_KEYS()} to return values that directly relate
to lastest call and forget whatever concerns previous calls.
It seems:
- on first call, HANGUPCAUSE_KEYS() returns an empty value,
- on second call, HANGUPCAUSE_KEYS() returns two values,


Is my expectation correct ?

Best regards
