Geräte-Journal auslesen: Ab Version 3.1.035 kann der CTI Client Offline-Anrufe aus einigen TAPI-Geräten auslesen. Diese Funktion wird unterstützt für: FritzBox-, Yealink-, Snom- und Android-Lines.

• Hier können Sie festlegen, dass die Anrufe bei jedem CTI Client Start ausgelesen werden. Dazu ist der Haken zu setzen bei: "Automatisch bei jedem Verbindungsaufbau zum TAPI-Gerät".
  Die Grundeinstellung für den Abfragezeitraum ist 30 Tage. Es werden aber nur die Anrufe seit dem letzten Beenden des CTI Clients übernommen.

• Wenn Sie erstmalig Anrufe auslesen wollen, können Sie den Abfragezeitraum kurzzeitig auf die benötige Tageanzahl setzen und dann "Geräte-Journal jetzt auslesen" klicken.
  Anschließend sollte der Abfragezeitraum wieder auf 30 Tage gestellt werden.

 Call signaling by sound card: Hint: If you phone via sound-card (e.g. in combination with an ISDN card), you should activate this option.

Fade out sound on calls: Activate this option to fade out the sound output of other applications such as media players or web browsers during phone calls. At the end of the call, these are fade in again. Further important information on configuration and requirements can be found here ...

This is a TAPI device of another user: This setting may affect the monitoring via a CTI Server Group panel. Only the calls of the "own" TAPI devices are reported to the CTI Server and thus displayed on the Group panel.

Activate call forwarding: When the lock screen is activated, call forwarding is set to the specified number. Any call forwarding that may already be set will be overwritten.
