The Caller ID Telephone Module (CTI)
Use the CTI Module of Xpert-Timer to time your incoming and outgoing phone calls.
To get the system running you need to add a phone number to your client in the client manager. Additionally you assign a project that's supposed to start, if the phone number is called or a call comes in. Now the time on the project will automatically start running. Once you hang up, the time stamp is stopped and the timer of the project you've previously worked on starts running again.
Xpert-Timer uses the TAPI interface of your telephone system when connecting.
