[Freeswitch-users] Asterisk dial status

Actually you have no other way except parsing channel events not only from
parent channel but from child channels too since there can be many child
channels in bridge attempt.
Actually, FS doesn't have a direct method like Asterisk DIALSTATUS. If you
answer incoming call and then doing bridge to some endpoint, you will see
ANSWER in disposition variables even in channel events.
I can be wrong, but I haven't found any other way as to parse hangup /
hangup_complete / answer events of parent and child channels to correctly
determine disposition, cause codes and so on in all cases.
