What is VOIP?

VoIP or Voice Over Internet Protocol, is the transmission of voice traffic over IP-based networks. Since its birth, it quickly became popular because of the amount of money an individual can save when it is used for long distance calls.

VoIP services are cheap, compared to traditional phones, and there is even software available to make free international calls. Unfortunately, these kinds of software only works for PC-to-PC calls. To take full advantage of VoIP, a VoIP phone is recommended.
