FireFly is an Internet Phone program, that allows you to talk to friends anywhere in the world, using the Internet and the free Firefly software. The interface is very easy to use, just punch the number of your (Firefly) contact, or select it from the address book. The program also includes a voicemail feature to keep track of calls while you are away or talking to someone else. The program uses your internet connection and voice over IP technology, so there is no charge for these calls. The people you call however need to have the FireFly software installed. We tested the software with an international call (USA to Canada and Australia), and the voice quality was excellent. Firefly Softphone can also make calls to regular landline phones, however this is based on usage charges.
