Known Limitations

Subject Description

2CIF/2SIF support

RSS can not encode 2CIF/2SIF as a standard resolution when

transforming to WMV file , the WMV file is not correct resolution , just

keep same scale with 2CIF or 2SIF , so the anemographic video will

be showed on PC .

Disable promotion on the VSX when working with the VSX

LAN Setting

The same LAN Speed need to be forced on the RSS side and in the

switch side.

Stereo support

SIREN 22 Stereo is supported for H323 Playback. When playing the

archive using windows media player - the archive will be played in

mono.

RSS takes a while to respond to a "stop recording" action at endpoint,

can not end and play IVR immediately.

RSS 2000 Can not support 2CIF live streaming, will convert to WMV

off line.

HD Endpoint

Embedded MP

integration

There is a limitation here , if you enable HD capacity of RSS , when it

become the first participant to connect HD endpoint with MP , HD

endpoint will send HD video format , but once the second endpoint to

join the conference , HD endpoint will send CIF format video to RSS ,

if you start recording before changing to CIF format , it means RSS

will save 720P and CIF format video in one WMV file , WMV file can

not support this , it will encode error. It is a known limitation.

We have 2 option to avoid this :

1 Disable HD capacity of RSS when connect to HD MP

2 After HD MP sending CIF format vide, start to record, before

other participants leave (if only leave RSS, will change to HD again)

stop recording.

I do recommend option 1.

FECC control with

Endpoint embedded



When RSS dial into endpoint MP, only when RSS is speaker,

customer can control RSS by FECC, but once speaker change to

other participant, it will be back never, so customer can not control

RSS by FECC.



When RSS dial into endpoint MP, if you press left key to hide the

menu, you will see the loop video on the screen, so don’t hide the

menu in this situation.

We recommend when working with endpoint embedded MP, please

don’t use FECC control, please just use DTMF.

Clustering Only support 10 H.323 playback, including local and remote playback.

Software shutdown

When use software shutdown command, customer need to turn on

the power switch after 2 minutes at least , otherwise the system might

not boot correctly .
