TapiRex shows a contact for an incoming phone-call with image, name and company. Microsoft Outlook is supported as source for the addresses as well as any other ODBC-database (like Access, mySQL, SQL-Server, ...).
The program can even show incoming calls on any telephone plugged to any computer in your network (client-server mode).

Any developer can extend the program with its open architecture. A free SDK is available. Many free plugins are available (like Speech output of caller, run any application on a call, notification and call history in Microsoft Media Center, ...).
