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)
• There are defined limits to the allowed number of simultaneous recordings in VEMS.
Any attempt to record more than the permitted number of streams from the gateway will
generate an error message in VEMS Mystro–but not in the DME. (541)
• VEMS Mystro 6.x plays Live Entered URLs of VC Gateway streams and recordings
made from the VC Gateway interface. VEMS 5.x supports Live Entered URLs only—no
recordings. (471)
• Content recorded from the VC Gateway will not play in QuickTime 7.7 on 32-bit
Windows 7 desktops. (425)
• Audio and video issues have been reported with Tandberg systems when using Internet
Explorer for incoming calls. For best results use Firefox. (378)
• Inconsistent behavior has been reported when playing back recorded VC Gateway
streams (and recordings of Live Entered URL gateway streams) on Macintosh desktops.
For best results experiment with the settings on the System Settings > Player Preferences
page in VEMS Mystro. (369)
Incoming Lines

To access the VC Gateway Incoming Lines fields:
1. Navigate to
VC Gateway Configuration
>
Incoming Lines
.
The DME can be invited into a video call by an individual video conference camera and
codec or by a multipoint control unit (MCU). When the remote video conferencing system
will be initiating a call to the DME, the VC Gateway is configured using the Incoming Lines
pages. The Incoming Lines page shows the line table. This table shows the current state of all
available incoming lines.
