the Interactive Voice Response Menu, proceed to “Chapter 5: Using the Interactive Voice Response Menu.”

• A router and cable/DSL modem (or gateway)
• One or more Ethernet network switches (so you can connect Internet phones or computers)
• At least one active Internet phone service account and its settings if you want to make external calls
• An active Internet connection if you want to make external calls

NOTE: For best results, use a switch that offers QoS (Quality of Service) and full wire-speed
switching. QoS enables the switch to give top priority to voice traffic, while full wire-speed
switching lets it forward packets as fast as your network can deliver them. The next best
choice is a QoS (Quality of Service) switch.
