VoIP phone systems use your internet connection to make and receive calls, so having adequate bandwidth is essential for good call quality. But how much bandwidth do you actually need? The answer depends on the number of concurrent calls, the audio codec used, and other network activity.
Each VoIP call typically uses about 100 Kbps of bandwidth. This guide helps you calculate your bandwidth requirements based on your team size and calling patterns, and provides tips for optimizing your network to ensure crystal-clear calls.
