I am looking for an app that can keep a log of all calls -- incoming and outgoing -- and show monthly reports that shows how much time we are spending on calls with which of our contacts.

I want to use this to analyze my phone usage (how much time and money I am spending per month on local calls, conference calls, calls to family, and long distance / work related calls)

Phone company gives me a itemized bill but it is not easy to filter / sort or combine with my contact list to easily filter for specific groups of contacts, etc.

Thanks!
