Variable hangup cause
From FreeSWITCH Wiki
hangup_cause
This is set to the hangup cause of the A leg of the call (note that as such it doesn't make much sense before the end of the call). Often this will take the hangup cause from the B leg of the call, if there is one. For a list of hangup causes, see Hangup Causes.
Usage:
<action application="log" data="1 A-leg hangup cause: ${hangup_cause}"/>
