The relevant number for you should be CPC duration. As previously, I recommend 500 - 750 ms. With settings in that range, you'll probably get the disconnect then reorder tone (or "if you'd like to make a call, please hang up and dial again" type recording, but more likely reorder).

If you set for 1000 ms or longer, it should work as well, but instead of reorder or recording, you might actually get a fresh dialtone.
