Description
When a Vcon ISDN endpoint connects
to a VideoSwitching (Auto or H.263)
conference the endpoint disconnects.
The Tandberg MXP endpoint connects
Secondary during Video Switching
conferences set to Auto and 768 Kbps.
When you delete an IP Network
Service on the MCU, the Card's
properties still appear as registered in
PathNavigator.
When entering an empty space in the
Alias field in the Participant Properties
call failure can occur.
In a mixed system with ISDN and IP,
when the clock is set to ISDN and you
set the source of the ISDN span to
Null, the IP+ card may stop
responding.
When two different ISDN Network
Services are used for two "Meet Me" or
Meeting Room conferences, and one
dial-in number is contained in the
other, dial-in undefined participants
may be connected to the wrong
conference. For example, if one
Network Service allocates the dial-in
number 397, and the second allocates
the number 8397, participants dialing
8397 are connected to the conference
assigned the number 397.
After participants disconnect from a
conference, the LED on the card is still
On (Active).
