[asterisk-dev] X-Asterisk-HangupCause header only added in auto fallthrough mode

[Klaus Darilion]

Hi!

Is this a bug or a feature I do not understand?

Simple scenario:

---SIP----> Asterisk ----SIP---->
         _X. => {
                 Dial(SIP/${EXTEN});
         }


If the outgoing leg is rejected (e.g. 480), Asterisk will add the 
X-Asterisk-HangupCause headers:

    X-Asterisk-HangupCause: User alerting, no answer
    X-Asterisk-HangupCauseCode: 19


But if the call is hang up manually, these headers are not added:
         _X. => {
                 Dial(SIP/${EXTEN});
                 Hangup(1);  // Hangup() does not work either
         }
This causes a SIP response without X-Asterisk-Hangupcause headers.

Why?

Thanks
Klaus
