So if i would like to achieve this scenario:
1. call is ringing on agent, and client drops call before the agent manages to pick up
2. the OnCallAbandon function is not called, because the interaction was outside of URS.
what is needed to be set up, to execute OnCallAbandon (or some other function), which will run strategy that collects information of dropped calls to database (ANI, DNIS, time, date)
When call is dropped in IVR, queue, OnCallAbandon is executed correctly.
