will not be available for video calls.
When you register the system to a RADVISION gatekeeper, you may
receive a message that says "Failed to Ping the gatekeeper." Ignore this
message.
This release supports the Auto ISDN feature for systems in North
America. Since not all network equipment supports Auto ISDN, you
should manually configure your system if Auto ISDN cannot determine
the network configuration.
If the system is configured to allow users to redial numbers, it retains
the last number dialed until you log off. If you do not want to save the
last number dialed, use AdminTools to disable this feature.
You must restart the system after you change the IMUX call mode using
AdminTools.
Systems configured for V.35/RS-449 do not publish their information to
the Central Directory. The system administrator must add this
information manually.
iPower and TeamStation systems use different formats for their local
directories. You cannot copy a directory file from a TeamStation to an
iPower system or from an iPower system to a TeamStation.
Logging On and Logging Off
iPower 900 systems running Windows XP operating systems may
periodically require user intervention upon system shutdown. Should the
system stall at the point where it would normally display the message,
"It is now safe to turn off your computer", you may safely power off the
system by pressing the power button to the OFF position.
iPower Collaboration software supports users who are members of the
following Windows groups: Users, Power Users or Administrators. Users
logged in as "Guest" may be restricted from accessing certain iPower
menu options.
You may experience problems if you change the Auto Logon user
information on a system that is already set up for Auto Logon. To
modify Auto Logon user information, configure the system to use
Standard Windows Logon. Then, configure the system to use Auto
Logon again.
Make sure you allow the iPower system time to complete its normal
shutdown procedure. Do not click the End Now button on the Ending
Application dialog box while the application is still running.
