Hello everyone,

I am doing my final year project now and need to build a caller id circuit to display the incoming call's number. Is there any circuit available online which i can apply in Malaysia? Because i know that different country may use different protocol and frequency. Thank You.

For the caller Id circuit, is it a must to program the micro-controller?? is there any method to do it in hardware without using programming?

There were Motorola caller id chips around, can't remember the designation. Also you have to know what sort of caller id is being used, the project in the post above is for a DTMF based caller id, frankly I thought all caller id was based on a 2400 baud signal Bell??
