Release Notes
V500 and VSX systems, version 8.5
Issue Description
Interoperability The following issues were seen in H.239 calls between V500 or
TANDBERG VSX systems and TANDBERG E series systems.
•
•
In calls between a V500 or VSX system and a TANDBERG
6000 B9.1 system and E4.2 with H.239 enabled, the call
connected and the V500 or VSX system displayed video
correctly, but the TANDBERG system displayed black video.
When H.239 was disabled on either system, video was
displayed on the TANDBERG system correctly. This has been
corrected.
H.239 was not supported in H.320 V500 or VSX systems
multipoint calls with TANDBERG systems. This has been
corrected.
In H.320 H.239 conferences with a TANDBERG 6000 MXP
MCU, a V500 or VSX system was unable to receive or transmit
content. This has been corrected.
The VSX system does not receive video in H.323 voice
activated switching conferences with the TANDBERG 6000
E4.0 MCU. The does not occur in continuous presence
conferences.
H.239 functions properly with TANDBERG E5.2 and MXP F4.1.
People+Content For best results sending and receiving content, use call rates
greater than 128 kbps.
Changing laptop resolution while sending content may result in
the far site losing content. If this occurs, stop and restart
sending content.
Do not change the People+Content quality preference while
sending content.
The far site can select a camera source on the near site for
content. The only way the far site can then stop this source is to
start sending content itself.
In calls to TANDBERG systems, if H.239 is enabled on the
VSX system but not enabled on the TANDBERG system,
content will not be sent to the TANDBERG system (though the
VSX system may report that content is being sent).
In H.261 ISDN conferences through MGC, content may not be
displayed.
In 128 kbps calls between a VSX 8000 system and a
TANDBERG 6000E, content from the TANDBERG system
were sometimes sent to the wrong display. This has been
corrected.
V500 and VSX systems did not always receive content in
calls with TANDBERG 880E systems. This has been
corrected.
