In a PathNavigator Conference on Demand call, only the local system is
included in the Conference Sites list. To include all sites, enable Chair
Control on the MCU.
Conferences hosted by an Avaya MCU do not support the Browse
function.If you select
Picture-in-Picture (PIP)
menu, you are unable to switch to near-end camera control.
When using an Ezenia! H.323 MCU, the call does not connect when
dialed with an E.164 address that starts with the digit "1".
When you use the on-screen Camera Controls, you cannot use the on-
screen cursor for functions outside of the Camera Controls, such as
muting. You can use the buttons on the remote control or a keyboard
shortcut.
A call must be at least 112 kbps to send Content. The system does not
send Content in a 56 kbps or 64 kbps call.
If you attach V.35/RS-449 cables to the system when it is powered on,
the system may interpret any signal changes as an incoming call. To
address this issue, power off the system before connecting the cables.
In a V.35 DCE-Signal call to a Concorde•4500 system, the iPower
system may hang up the call and not reconnect. To address this issue,
configure the iPower system for DCE-Dedicated calls when placing or
receiving non- dialed calls from a Concorde system.
In V.35 DCE-Signal calls, a Montage system does not disconnect
properly from the iPower system. To address this issue, configure the
iPower system for DCE-Dedicated calls.
Use the following encryption type settings with the call modes listed
below. All other settings are invalid:
Encryption Type Call Mode
KG-194
KIV-7
None
If you are using encryption in a DCE-Dedicated call, the call may take
up to one minute to completely disconnect from the system.
iPower does not support these types of 2x64 calls:
– 2x64 calls where both channels are dialed simultaneously
– Non-dialed (DCE-signaled or DCE-dedicated) 2x64 calls
Dialed V.35/RS-449 2x64 calls may take up to 20 seconds to receive
remote video.
On 900 or 9000 systems (V.35 or RS-449) using a Lucent/Ascend IMUX
in Dialed mode, the IMUX may sometimes get into a state where it
cannot place or receive 2x64 kbps or 2x56 kbps calls. If this occurs,
