I don't know the type of phone system here, except that it is a large PBX system. My direct line is 212-493-XXXX. When I dialed the call direct, with 9-1-800, it read back 212-968-XXXX. Dialing this number produced endless ringing; it is not recognizable to me as a company exchange. 3) I then dialed 9-0 for the New York Telephone operator, who put the call through. The report was 212-555-5555, so apparently the ANI was defeated in that case. 4) I then dialed 9-0 again and asked for the AT&T operator, who told me that she couldn't put through a call to a non-AT&T 800 number. (As others have stated, the 800-666 prefix is owned by MCI.) 5) Finally, I dialed 9-00 here, which got me an MCI operator. MCI is the bank's long distance company. The MCI operator stated she could not dial an 800 number call, even to an MCI 800 number! I had the call transferred to a supervisor, and finally to MCI customer service. Customer Service's first attempt to get the call through failed due to a busy signal. 6) I repeatedly dialed MCI Customer Service at 800-444-3333. I want to note here the contributions of Susan Cozza, who did most of the work with me. (I told her and other MCI customer service personnel that my PBX was unable to dial 800-666 numbers due to a software fault.) Each time they attempted to place the call for me, the line was busy. Susan checked and stated that there were an insufficient number of trunks on that line to handle the call, since the recorded message was unusually long, and that I should keep trying. 7) Finally, Susan got through. I expected another 212-555-1212 ANI failure. What I got, though, was 914-939-XXXX! A check with 914 DA informs me that this is a number in Portchester, NY, a suburb north of NYC. I called back to 914 DA and asked for MCI in Portchester: I received a 914-937-XXXX number in Ryebrook, the next town over. (Probably they share a CO.) All in all, an interesting experiment (hack?). cowan@marob.masa.com (aka ...!hombre!marob!cowan)
