TAPI lines

You can set up the connection to your telephone system here and select which extensions are to be made available in the network.

The connection to the telephone system is displayed as "Line group". If an ECSTA is set up, you can select "Configure driver" in the context menu of the line group to enter the connection data to your telephone systems.
If the TAPI driver of the manufacturer is used, the setup is done via the Windows® control panel "Phone and Modem".

After successful connection and line setup in the TAPI driver, the lines are displayed under the line group.
For information on setting up a supplied ECSTA for your PBX, please refer to Connecting PBX via ECSTA.

Line group properties
The properties of the line group apply for all lines of the group. To display the properties of the group, highlight the group and select Properties in the context menu. The configuration options are explained in line group properties for TAPI drivers.

Line properties
You can change some line properties directly in the list. A dialog can be opened via properties after selecting and marking a line. A line has the following properties:

• Use lines
  The line is opened by the estos UCServer. Then the line can be used and users can be added.
• Trunk line
  This line is treated specifically in estos UCServer if it is an outside line.
• Activate journal
  All calls on this line are written to the database.
• Private telephone
  In the journal all of this phone's entries are automatically marked as "Private" and are treated according to the rules of the Telephone journal. Other users are not able to see connected numbers or contacts on this phone.
• Line addresses
  If the TAPI line has several addresses, you can define here whether incoming calls are notified to all addresses or only to one special address.
• Internal phone number
  This is the phone number with which the phone can be contacted internally. The number is normally determined automatically (either from the address or from the line name). A phone number may only occur once. This phone number is the unique key with which the phones are assigned to users and computers. If you have dual phone numbers such as, for example, with parallel connection of terminal devices, you should use small letters to differentiate the phone numbers. If you have two lines with the phone number 111, you should give one line the number 111 and the other the number 111b.
• Location
  Defines the Location of the line, if the location wasn't configured via the line group. The location defines, for example, the number formats and the dialing rules.
  
• Call redirection
  estos UCServer supports server-side call redirection. Various call targets can be added to the list of redirections. How long a call remains at the relevant extension if it is not answered must be additionally configured. The list of the first line which rings applies. Configured call redirections on lines which are gone through as part of a call forwarding scenario do not apply. All targets in the list must be activated by the server in the line manager. If a target is not monitored, the forwarding is stopped at this number.

Line status
The line status, whether available or not, is displayed in the form of a colored icon. If a ECSTA driver is used, the tooltip schows detailed information on the status icon in case of en error (communication error, login error, license error etc.).
