You're on the right track.  I have a couple of comments:

1) You may want to check for AST_SOFTHANGUP_ASYNCGOTO using a bitwise
and instead of equality, to be consistent with how the value is being
set it ast_softhangup_nolock().

2) Checking for this value will only work for channel's executing the
dialplan.  In your case, for channels in MeetMe, that is most likely the
case, but it's not definite.

For example, you can do an originate with the target being a specific
application and not an extension.  In that case, the channel will not be
executing the dialplan.

For channels not executing the dialplan ... I honestly don't see a way
to be able to determine what happened.  It's going to look like a hangup
(a masquerade will have happened).
