The RMX Web Client supports monitoring of H.263 4CIF information. The H.245 or SDP tab
includes the additional information.
The creation of a new H.263 4CIF slide is supported in the IVR Service in addition to the
current H.263 IVR slide. If users utilize the default Polycom slides that are delivered with
RMX 1500/2000/4000, the slide’s resolution will be as defined in the profile, i.e. SD, HD,
CIF, etc.
For more information see “High Resolution Slides” on page 16-16.
