Normally, when I call one of MCI's, SPRINT's or AT&T's 800 numbers, my number will show up on the called party's call detail. If I simply Dial "O", and "have trouble reaching 800-xxx-xxxx" the call detail doesn't have my number. (Yes, the TOPS operator does have it.) I've only tried this with the above-mentioned 800 providers. My question: Is this just a fluke ? Is there some type of convention for TOPS to pass the calling number to the 800 service provider ? Has anyone else tried this ? Does it work elsewhere ? On a related question: For those of you with Caller*ID, what happens when you get a call routed through the "O" operator ? (the called party being someone that you would normally get a calling number from on your Caller*ID display). Steve Internet: slr@riot.caltech.edu UUCP:....elroy!cit-vax!riot!slr US MAIL: P.O.
