caller id with mt8870

It's not problem with your circuit as you are getting the numbers you type on your phone on display. The problem lies in either your Telephone Company is not sending the Caller ID info or you connected the caller ID module to the line after hook switch. Either case please check in this way, first confirm the Caller ID format in your area is DTMF & not FSK. Then check the Telephone Company is providing you the CallerID infromation. Hope this helps..
