asterisk users - Feb 2017 - PJSIP hangupcause how to

if a PJSIP call fails, how can I capture SIP code, like 503,603 etc?
in old SIP channel, we had ${HASH(SIP_CAUSE,<channel-name>)}
but in PJSIP it has to be the outbound channel, which is gone when the
control returns to the calling channel.

This functionality was replaced quite some time ago with HANGUPCAUSE[1].
