We all know the basic codes to make our phones do stuff like call back (*69,) block caller ID (*67,) etc. However, there are a lot more of these codes that aren't widely known. For example, Verizon's call trace can be accessed by dialing *57. I'm pretty sure that *87 and *82 can be used to block and unblock private numbers on most carriers.

Now here's the part where I turn to you: I used to have a complete list of star and pound codes for all major long distance and wireless carriers, and I lost it during my last reformat. These are all legal for public use, but they're kept quiet by the phone companies (that makes it sound like this should go in paranoia.) There was one in particular that I liked, which could oveerride the "all carrier lines busy" signal by attachign a "priority call" flag to a number that was preceded by this code.

If anyone has a similar list (I compiled my own based on public sources and bits of info I pried out of phone co. employees,) I would be unbelievably grateful if you would share it.
