Bandwidth andQuality of Service (QoS)

Each concurrent VoIP call consumes approximately 85- 120 kbps of bandwidth (depending on codec). A consumess with 20 consumes calls should reserve at least least 2 Mbps dedicated to voice. QoS tagging (DSCP) on routers prioritizes voice packets over data traffic, preventing jitter and echo.
