Polycom iPower 600 Installation Instructions Manual page 8

Tandberg supports H.264 at CIF resolution. Calls with Tandberg that
use H.264 will down-scale Content sources (such as the Windows
desktop) to CIF resolution, with a resulting loss of video quality and
sharpness. To work around this issue, configure the iPower system
to use H.263+ video.
