Bandwidth is the fundamental requirement that there be enough space in a network path for all of your packets to get through unimpeded. When it comes to bandwidth and conferencing more is always better. IP-based H.323 video calls typically use bandwidth of around 384-768Kbps plus overhead because of the packetizing overhead of IP. This bandwidth should be symmetric — meaning each end should be able to both send and receive the same amount of data for the call. Here are some guidelines for IP videoconferencing and video call quality. Circuits are full-duplex. You need to add about 30% for overhead to call speeds desired. • 384 Kbps + 30% = 499.2 Kbps • 512 Kbps + 30% = 665.6 Kbps • 768 Kbps + 30% = 998.4 Kbps • 1536 Kbps + 30% = 1.996 Mbps • 1920 Kbps + 30% = 2.496 Mbps Multiply by the number of simultaneous sessions that you desire.
