My system has been working great until I wanted to use the Caller ID functionality. We have an automated attendant answer all the incoming calls and then the caller enters the extension. All I want is to pass the caller id info to the extension. I can't get this to work right ... I did get this to work with some crazy forwarding but this caused all the lights on the phone (KX-T7730) to blink for each extension. Is this possible to do? I feel I am missing something simple.
