Source note · Codec selection and bandwidth planning
Vendor planning figures are not directly comparable, because each source defines its unit differently: Webex Calling gives 100 kbps per audio stream, Zoom Phone 60-100 kbps per call, Teams 58-76 kbps up/down per endpoint, and Webex Contact Center WebRTC at least 100 kbps per call. None of these pages states the header overhead it includes.
