Keeping in-progress installs & installed programs from "phoning home" ?

I’ve installed CFW and configured it according to the instructions here:

I did use the option "“Alert me to incoming connections and make my ports stealth on a per-case basis”.

Everything appears to be working great.

I do want to be sure that if an ongoing install or already installed program tries to “phone home”, CFW will alert me and give me the option to allow/block as I choose.

Is there anything else I need to configure in order to assure that I am alerted and can make a choice ?

Assuming that the Firewall Security Level is set to Custom Policy and Do not show popup alerts is disabled, then I believe that it should behave as you expect.
