Release Notes
V500 and VSX systems, version 8.5
Feature Limitation
Video VSX systems do not support Pro-Motion in internal multipoint
calls.
When Polycom Video and Audio Error Concealment
engages or disengages in a call, the monitor switches briefly
from far-site video to near-site video, then back.
VSX systems send video in low frame rates when using a
camera set to Sharpness.
Pro-Motion provides superior video quality by transmitting
video in a format similar to that used by the camera and
should only be used in calls between endpoints that use the
same camera format (both PAL or both NTSC). VSX systems
improperly activate Pro-Motion H.264 in calls between a PAL
VSX 8000 and an NTSC VSX 8000. This can result in video
artifacts in scenes with high motion. To work around this
issue, disable Pro-Motion in calls between a PAL VSX 8000
and an NTSC VSX 8000.
Web Interface SIP registration status is not displayed in the web interface,
but it does show up on the system interface.
For security reasons, the web interface does not include
some of the configuration options available in the system's
user interface.
Web Director on VSX Web does not give the remote
administrator any way to start or stop Polycom
People+Content IP.
When completing the out-of-box setup through the web
interface, the administrator is presented with the option to
select H.323 or SIP. Polycom recommends selecting H.323
at this point. The SIP selection can be enabled after the
configuration is completed.
Note: Making changes between these two selections causes
the system to restart before the changes can take effect.
The web interface does not give access to the following
utilities: Calendar and Call Scheduler.
The web interface Call Summary page (Diagnostics >
System Status > Call Summary) does not include a Serial
Calls section listing V.35 calls. The calls are included in the
total call number. To see a listing of V.35 calls, refer to the
system user interface.
