[[Voice over IP]] (VoIP) software is used to conduct [[telephone]]-like voice conversations across [[Internet Protocol|IP]] based networks. For residential markets, VOIP phone service is often cheaper than traditional [[PSTN]] phone service and can remove geographic restrictions to telephone numbers (i.e. have a "New York" PSTN phone number in Tokyo).
For enterprise or business markets, VoIP enables the enterprise to manage a single network (the IP network) instead of separate voice and data networks, while enabling advanced and flexible capabilities to the end user.
