TAPI lines

Here you can select which extensions will be made available in the network.

A line usually corresponds to a phone. All lines are displayed in the list which are available on the computer.
The lines are made available by SIP registration for SIP-Softphones or by TAPI drivers. 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.

Add a line (PBX)
estos UCServer supports central connection to telephone system through the system manufacturer’s CTI TAPI driver, through the supplied ECSTA connection or through SIP softphones. The TAPI driver and ECSTA connectors allow monitoring and remotely controlling telephones that will be operated with the system. The SIP Softphone Configuration will allow ProCall Client users to use their PCs as softphones in order to make calls through the telephone system.

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 group properties
Lines are combined into groups. The properties of a group apply to all lines in the group. To display the properties of a group, select the group and press Properties. The settings for the Line Group Properties for SIP Softphone and Line Group Properties for TAPI Driver differ in a few respects and therefore have separate help pages.

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.).
