1. Is there a programming (or other) solution to the ringing delay?

2. Is there another solution using analog port (or other method) vs using the CO line? Aside from solving the ring delay customer could use the CO line that's currently dedicated to the door phone/strike

There is no such thing as a 128C. Depending on what system it actually is there are some proprietary options if it is new enough.
