NOTE: A channel consists of transmitting and a receiving side, so the bandwidth is double for a bi-directional audio stream.

NOTE: Bandwidth values are approximate maximums, actual bandwidth used could be considerably lower with VAD enabled.

Codec: Determines how the audio is compressed/decompressed and the name given to the

defined algorithm.

Codec Rate: Actual bits/s of the audio in the compressed form. This is sent over the network

through various data packets. Network efficiency can be calculated with IP header for each

packet of X ms of audio.
