It works with devices that support TAPI protocol and can be used on an unlimited number of lines.

Ideal for call centers based on asterisk  (trixbox, freepbx etc.). Also can be connected by simple or isdn modems that support TAPI (fritz card).

It produces a text file containing the list of calls received per day.

If you want your software to support callerid function, WhoIsCalling? is the easiest solution.
