Maintenance Manual

No common audio formats, No common video formats
These messages indicate that the remote endpoint had declared
media capabilities including codecs that the MCU was permitted
to send, but that the MCU was unable to transmit the specific
formats declared.
This could occur if, for instance,
the far end's advertised receive
video sizes were all 4CIF (704 x
576 pixels) or above, and the
MCU was set to not transmit
above CIF (352 x 288 pixels).
No common symmetric audio codecs, No common symmetric
video codecs
Indicates that the MCU was unable to open a media channel to
the endpoint because the only possible channels it would be able
to open were invalid due to a symmetry clash. This clash occurs
when the remote endpoint declared that it is only able to receive
certain types of media if it is also sending the same format, and
the format in question is one that the MCU is able to send but not
receive.
Audio port limit exceeded, Video port limit exceeded
These messages occur if a channel was unable to be opened
solely because doing so would have exceeded the port limit. This
limit may be a per-conference restriction or, for those
conferences which impose no such limit, it could be that all of the
MCU's available ports were in use.
Endpoint audio and video channels rejected, Endpoint audio
channel rejected, Endpoint video channel rejected
Indicates that the MCU is unable to receive the media format that
the endpoint is trying to transmit.
Tx: briefly describes the audio and main video streams
transmitted by the MCU to this participant.
Rx: briefly describes the audio and main video streams received
by the MCU from this participant.
The description typically includes
the resolution, bitrate and codec
used by the media stream.
However, if a channel is muted,
the description may be indicated
in the Rx row, for example, as
"muted remotely" (for H.323
endpoints) or <no video> (for SIP
endpoints).
