Hi everyone. I am trying to install Vista Caller Id on Windows 7 and it doesn't seem to work correctly. I am not getting any calls displayed on the Pc. I downloaded the Vista caller id client and the server. I made Windows 7 the server and the two Vista machines the clients. Does the modem have to be caller id ready? I have an old modem I uninstalled from my Windows XP computer. What is Tapi or Capi. Which one do I have? I have a Comcast setup with the telephone included on the external modem. Any help will be appreciated. deanie44
