you can use a dtmf to bcd decoder.you ll get a bcd output which you can interface with a µc and do whatever you want.once i used this to interface with a mobile phone to control 4 switches of course you can control more .heres a schematic which you can connect to landline and control 4 switches.you need to dial the landline and press 0(im not sure if its 0) aftr it rings u ll b able to control switches then.this circuit doesnt use µc but the output of ickt 3170 can b connected to µc rest circuit can b om.itted
