[Freeswitch-users] Getting call leg details

I have a event socket listener that catches CHANNEL_HANGUP_COMPLETE events and I want to verify the call leg details 1. Did the call end in aleg or bleg 2. What was the call durations in each of the legs I am not sure if I am applying the terminology of call legs in the proper way but what I mean by aleg is that the incoming call was not bridged and bleg after being bridged
