[Freeswitch-users] [In Progress/Ringing Calls][FreeSWITCH Event]

Hi Users, I am trying to get in progress call event from freeswitch, i saw that we have channel_progress and channel_progress_media events, but those are not getting executed all the time. Can someone guide me what event i need to capture to show current running calls, basically it would be a simple counter getting increment on new channel in progress/ringing and decrement on channel_hangup_complete event.
