Every once in a while, someone posts a note asking about ringback codes (numbers to dial to make your own telephone ring). Unfortunately, these codes aren't the same everywhere, and are mostly undocumented. I've discovered the following method of making my own phone ring, and it should work everywhere. It only rings the phone once, but if all you're interested in is verifying that you can recieve calls, that's all you need. It requires that you have Call Waiting on your line, and you also need an AT&T phone credit card. Pick up your phone and call your own number using the credit card. You should hear the Call Waiting tone immediately, followed by the ring tone. Hang up; your phone will ring once. This doesn't work if you just try to direct-dial your own number, even if you have Call Waiting. Your CO is smart enough to know that it makes no sense to allow you to call yourself. Using the credit card (apparently) bypasses your CO. --Pat.

Using the credit card (apparently) bypasses your CO. At least on GTE in Torrance, the CO is not all that smart. I am able to dial my own number, hang up immediately, and have it ring once... _john -- John T.
