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 .
RSS2000 Can not support 2CIF live streaming , will convert to WMV off line .
HD Endpoint There is a limitation here , if you enable HD capacity of RSS , when it become the first
Embedded MP participant to connect HD endpoint with MP , HD endpoint will send HD video format , but
integration 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
