VC Gateway Configuration
VC Gateway Overview
Video conferencing enables people at different locations to see and hear each other, and to
share access to documents, slides, and desktop applications. Each site typically has a video
camera, a display device, as well as a microphone and speakers.
The DME video conferencing solution builds on a simple video conference by delivering a
multi-vendor, standards-based stream that lets smartphones, tablets, PCs/Macs, and TVs
display the video conference. It provides a cost effective way to leverage existing video
conferencing investments by delivering the video conference audio and video as a stream to
other elements in the Vbrick ecosystem. The stream can be centrally managed and delivered
to thousands of users across multiple sites. It can also be recorded for subsequent
on-demand viewing.
VC Gateway Caveats
• Intermittent error messages may pop up if an incorrect destination is configured on an
outgoing line and a call is made. Clicking okay and ignoring allows the user to proceed. (D-
03835)
• An outgoing call in alerting status is unable to hang up from the DME. Instead, the user
at the destination must decline the call. (D-03834)
• If the video resolution or other parameters of the incoming VC Stream changes most
RTP players will not continue to display video correctly. Restart the player. Flash players
using RTMP or HDS, Set Top Boxes using transport stream and HLS players will usually
play through the changes. (820)
• The Polycom HDX 8000 MCU only displays a split screen view when two endpoints are
connected. To avoid video problems, the DME must be connected last.
• Incoming calls from Polycom systems will not connect if you change the default SIP
Port. Therefore do not change the default SIP port. (446)
• If you change the default SIP Port on the System Configuration > Port page, you will
need to append the new port number to the
Line Identity
for incoming calls as in the
following example:
sip:<line_name>@<dme_ip_address>:<sip_port_number>
(565)
• If SSL is configured on the VEMS Mystro server, you must use a host name (instead of
an IP address) when configuring the
VEMS Mystro Address
on SIP
Defaults
page. (487)
• If category permissions are changed on the VEMS Mystro server, it may take up to 30
minutes before the category changes are shown in the DME. (498)
Note : If you purchased the Video Conferencing feature, the license for
this feature must be activated before the VC Gateway Configuration
option is shown in the DME's Configuration Menu. For more
information see Activate Feature.
