The Collaboration Server 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 the Collaboration Server, the slide's
resolution will be as defined in the profile, i.e. SD, HD, CIF, etc.

The CP Resolution Decision Matrix

All the CP resolution options and settings are based on a decision matrix which matches video resolutions
to connection line rates, with the aim of providing the best balance between resource usage and video
quality at any given line rate.
The following factors affect the decision matrices:
