Using the telnet protocol the program connects to you IPPhone adapter and logs incoming and outgoing calls. Busy-calls are also detected and logged. It also shows the dialpad when you dial. Build up you own phonebook so when your friends and family calls you the IPPhoneCallerId will show their phonenumber and name in the middle of your screen. If the number is not known (if you haven't updated your phonebook) the IPPhonecallerid takes you to any public phone directory of your choice with the unknown number as a parameter. IMPORTANT. When purchasing the code you will receive is based upon your PHONE number. Please ensure it is correctly entered when ordering.
