VoIP telephony

Introduction

Voice over internet protocol (VoIP) is a way of enabling voice conversations over the internet or any IP network. Internet telephony is a popular use of VoIP and can be used to save costs on phonecalls by routing those calls over broadband internet instead of the phone network. A fuller explanation can be found here and the Wikipedia definition here.

Examples
