Your post is quite ambiguous. What are you requesting? Obviously it is something to do with numeric codes and call screening but which RingCentral product are you talking about? How do you want it to work? Why do you need this "feature"? It would be nice if you flesh it out a lot more and possibly give an example of the situation you have and how you would like it to be.
You can use a lot more room to describe your feature request....you're not limited to one sentence.
