While not absolutely necessary, a broadband Internet connection is what makes your Internet phone calls reliable, and understandable. VoIP uses a traffic engineering term called Quality of Service (QoS) that refers to the implementation of controls to ensure that delay sensitive IP packets are prioritized as they flow through the pipe. To forgo these controls would result in acoustic problems like jitter and echo, as well as dropped calls. Because a broadband pipe is much larger than a dial up connection, there is much more throughput capacity, or space, to allow us to prioritize.
