From the developer:
Dialogue is a simple Mac application that uses bluetooth to connect your Mac with your phone. It allows you to answer and make normal phone calls over your Mac. After connecting your phone, the program warns you of incoming calls. You can also search for a contact on your address book or type in a phone number to make a call. Furthermore, Dialogue lets you record your conversations to play them back over and over again.
