Note
: The network bandwidth necessary to send the encoded audio is typically 5~10% higher than the bit rate due to pack-
etization overhead. For example, a two-way G.722 audio call at 64 Kbps consumes about 135 Kbps of network bandwidth.
The following table lists the audio codecs supported by each phone model:
