Looking through the app_dial code it looks like the peerflags gets set upon
hangup. If you can get access to that (not sure where your code is located)
then you should be able to check the OPT_CALLER_HANGUP value for that.
Another alternative maybe is the hangupcause as it gets set on the channel
too when hung up so you might be able to retrieve that and check it for
some value, but not sure if the causes will give you what you need.
A third way is to check if the channel hung up using the "ast_check_hangup"
or "ast_check_hangup_locked" function (maybe the best option?).
