Description
Sometimes ISDN endpoints fail to
move from one Video Switching
conference to another when the line
rate of the destination conference is
higher then the line rate at the initial
conference.
In reserved conferences with enabled
recordings that are configured to start
immediately, the first participant in the
conference continues to hear music
even after others have joined.
In a VSW lecture, ISDN or IP
conference, you can not force a lecturer
from the MGC Manager conference
properties.
In an H.320 Only conference with
Lecture Mode and Auto switching
between participants enabled, the video
of the Lecturer does not synchronize
each time that new participants join.
On an XPEK MCU, when extreme
packet loss occurs, the MGC Manager
can loose connection with the MCU.
During MCU dialout, the PVX endpoint
connects as "Secondary" when the dial
out call is set to H.263 and the endpoint
VGA Encoding is enabled.
When you switch between endpoints in
large Video Switching (86 participants)
conferences with 128 kbps line rate
using H264 video protocol, an assert
error and poor connection between the
MCU and the MGC Manager resulting
in an auto reboot.
The endpoint doesn't change mode
from QCIF to CIF in H264.
VTX1000s in wideband connections do
not provide DTMF feedback tones.
