Isdnserver is a server that can decode the hex values provided by your ISDN channels (B or D channels, depending on how your configuration is set up). It can send data like the phone numbers, the charging units, and the duration of a call to a predefined port, the console, or a user defined device. It can also be used as an answering machine.
Kisdnmonitor is a KDE applet for isdnserver. It monitors the B-Channels of your ISDN cards, shows each incoming/outgoing call in a popup window, calls while the user was absent and logged out (the PC has still to be powered on), the duration of a call, the costs of outgoing calls, and a list of all calls with editing and find options. It allows printing the list in the row order and sorting order you set up. Totals are calculated (time, duration, and costs). It is linked to kaddressbook (edit amd insert). It shows email addresse(s) of the caller in the context menu (if available), and statistics to graphically view the data. You can configure the main window toolbars.
