Billing and crd to callshop

Hi folks.

I am looking for a system that could provide billing and cdr to callshops.
Numbers dialed for extensions, durations, destinations, times, audio record by extensions, and when I want close the account to billing, I could throw away audio record.

Something really simple. I know A2Billing, but seems to be very professional and too much complicated, 'cause there's a lot of features inside.

I search for something that I can include price to sell for locations like 1X. to USA, 55X. to Brazil and so on.

If anyone have something ready, please let me know.

Thanks.
