Get your application built.
Would like to know:
What if the contact that is not saved is important, do you want to give functionality of direct decline or option to add?
Would like to integrate true caller to know who is the caller (Just in case if call is imp)
Call will be terminated directly after 3 minutes? Or would like to give a warning message of 3 minutes are consumed?
What-if call needs to be extended for more than 3 minutes?
