Active Calls Question

Active call logs API not only keeps the track of Active calls but also keeps the track of most recent calls. The recent calls stays in the Active calls for 20-40 min.

While it takes sometime for the most recent call to appear in the call-logs generated by call log API, Active Call API  allows the look up for the most recent call as well as the on going call data.  

Okay thanks! That makes sense. 
Thanks for your response!
