[vstudio3k]

Hi all,

My group is working on telephone remote control. We built a devices installed in telephone line from residential house that can turn on certain things around the house such as light, tv, etc. We have a few problem right now such as caller ID detection.

We can get signal and decode with (DTMF: MT8870) and microcontroller (PIC16F84A). Our device pickup the phone after 3 rings and able to turn on various things now. We are trying to write a code receive caller ID, so microcontroller can pickup the phone automatically, but we are not able to find any valuable information to finish it.

Please help us
