I been under a project of Interfacing 5 Telephone lines with a controller (PIC18F452). The overview of this project is to get the caller number and store it to memory. can you guys please help me about how to interface the telephone line with PIC. I have a basic idea and would like to share with you.
I decided to use a decoder to decode the Signal and to receive the number. If it is possible?.Also, i would like to know that a single controller is enough to interface with 5 telephone lines. if any website has the schematic please provide and help me.
