Quickly identify your longest and most expensive calls for your whole organisation, or for a specific group of extensions. This is useful for uncovering abuse, or for identifying certain types of calls which could be avoided, eg. Directory Enquiry type calls, whose function may be better obtained from other sources, eg. the internet.
Choose particular extension groups, or even individual extensions.
Select between incoming or outgoing calls only, or both.
Sort the results by cost or duration, and choose the number of ranking places you prefer - your top 10, top 50, top 100, or any other figure that best suits your needs.
