For this setting the callback entry must be set to 'Call back the remote site after name verification' (or must be set to the value 'Name' in WEBconfig or in the console). In the peer list one telephone number must be specified.
Some Windows versions (especially Windows 98) prompt the user to confirm the callback to the telephone number stored in the LANCOM ('Administrator Specified') with an input window. Other Windows versions only inform the user that the PC is waiting for the callback from the LANCOM.
The callback to a Windows workstation occurs approx. 15 seconds after the first connection has been dropped. This time setting cannot be decreased since it is a Windows default setting.
