Here you can select which extensions will be made available in the network.
A line usually corresponds to a telephone or a ProCall as a softphone. In the list all lines are displayed, which are available on the computer.
The lines are made available by SIP Line Registrations or as TAPI lines.
The TAPI drivers should already be installed on the system. If you add a new driver under Control Panel - add Phone and Modem Options and the lines are added here accordingly. With some TAPI-drivers it is necessary to reboot estos UCServer.
The configuration of the lines and line groups depends on the type of line.
