AUDIO Audio rate (kbps bandwidth) of the conference and the endpoint
must be the same but not necessarily their mode. When the audio
rate of the conference and the endpoint are different the endpoint’s
audio will interwork but the endpoint’s video will be invalid. MCU may
or may not send video to such an endpoint.
Table 8-5
summarizes expected endpoint audio mode with different
configurations of transfer rate, facility bandwidth, conference mode,
and whether or not all endpoints support the highest common audio
mode (HC audio) when the administered mode is auto. The highest
common conference mode is dependent on the administered
bandwidth. A ‘-’ in the table indicates ‘does not apply.’

AUDIO
(cont’d.)
Other possible AUDIO mode values include neutral (neutralized
I-channel) and Au-off, Frm (no audio signal) which never match
conference mode and are not supported by MCU.
