Description
Incorrect CLI's are assigned to
undefined T1-CAS participants.
Connecting and disconnecting T1-CAS
participants can prevent the transfer of
DTMF codes from the remaining
T1-CAS participants to the MCU.
T1-CAS is not supported on the
MGC-25.
When an ISDN participant connects to
a Video Switching (Auto or H.263)
conference the endpoint disconnects.
Video card units may fail when
terminating large CP conferences
before all the participants have
disconnected from the conference.
When resetting the video units quickly
(one after the other), the video card
status changes to Major.
Video force settings are not saved
after interactively (Drag & Drop)
moving a participant from an Operator
conference to the Home conference.
On QCIF endpoints the supported
layouts are up to 3x3 only (not 4x4 for
instance).
When moving an endpoint that
supports H.261, H.263 and H.264 from
a Video Switching conference set to
H.261 to a Video Switching conference
set to H.263 or H.264 it connects as
Secondary. When disconnecting and
reconnecting the endpoint it still
connects as Secondary.
When an FX endpoint connects to a
conference set to 4CIF & 15 fps and if
the conference video format changes
to CIF or QCIF, the MCU connects the
endpoint at 15 fps, although it should
have connected the endpoint at 30 fps.
A Video Switching conference
reservation with 4CIF Video Format
and 15 fps Frame rate settings, the
conference starts with CIF - 30 fps
settings.
