status conference
XRATE XRATE may be 64 when the endpoint is just dialing in, or in the event of
problems. It implies that only one B channel is being used.
(cont'd.)
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 7-48
configurations of transfer rate, facility bandwidth, conference mode, and
whether or not every endpoint supports the highest common audio mode (HC
audio) when the administered mode is
conference mode is dependent on the administered bandwidth. A '–' in the
table indicates 'does not apply.'
