When calling an 800 number from my Pasadena, CA exchange (818-794 - 1AESS), I have found that I can prevent the called party from receiving my number simply by routing the call through the "O" operator (Pac*Bell's TOPS). 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.

Your number is being passed (via ANI) to TOPS. TOPS *should* pass the caller's number back to the originating CO via ANI. If the originating CO has SS7 or ANI trunks to the 800 carrier, then the originating CO *should* forward your number to the 800 carrier. Possible causes : 1. TOPS is not passing the digits back to the CO; 2. the originating CO does not have ANI/SS7 trunks to the 800 carrier; 3. the originating CO does have such trunks, but for some reason is not forwarding your number. Since your number does usually get passed on, that should rule out #2. Someone who knows more about TOPS could address #1. If you know what type of CO you are served by, we might be able to address #3. --
