I >believe that the BOC does the calling card validation and handles the >billing in this case.......... John may have misinterpeted Eric's question, which I will attempt to clarify here. Eric's question would work for MCI since MCI *has* installed Automated Operator Positions (AOP's) in their network now, and subscribes to (I believe) 3 card authorization service companies. So, when you do dial 10222+1+NPA-NXX-XXXX, you should get a bong, and it should be MCI's AOP answering (you can let it time out, and it should go to a MCI TOPS operator). Now, the caveat is that the payphone will probably be programmed to intercept the call and go to an AOS (in the case of COCOTS only) in which case you have NO idea who is handling the call, and charging whatever outrageous amount to make that call. The incoming MF signalling from the local telco determines if the call is coming from a public or private payphone, and the MCI switch sees it is a 0+ call, and then sends the call to a switch which has an AOP (very few switches have AOP's still as of 6 months ago), then the usual AOP processes apply from here on. John's answer would be true, though, if you attempted to make an intra-lata call (within your service area), because the local BOC's don't subscribe/have access to the alternate L.D. carriers calling card databases. They only have access to AT&T's at the present time, though, this may change. BTW: MCI's AOP's are IBM PS/2 - Model 80's. >........................ If you have any volume discounts with these >carriers, your FONcard or MCI card calls would contribute to them, but >using your BOC card probably wouldn't. (You probably wouldn't get >your MCI "Around Town" discount either.) I was attempting to find out of the MCI Around Town discount was going to apply to BOC card calls, and the initial answer was 'No'. The problem was that Around Town determination was done at MCI's billing centers, not at the switch, and it was determined also by your *issued card number*, not the billing telephone number. I found out about this in my customer service days there, and the trick is to change your telephone number to that area's prefix, issue a card, then change back to your regular telephone number, and volia...you have 2 MCI cards with 2 around town areas. One area was based in San Rafel, and the other was based in Hayward (both in the San Francisco Bay area). Since the San Rafael card covered Marin and San Francisco for around town coverage, and the Hayward card covered the East Bay, I had Around Town coverage for most of the whole Bay Area! It was fun! Now that MCI has BOC billing, this trick could be a little harder since now MCI's computers do a check against the BOC's databases (this only applying to Pacific*Hell's........Pacific*Bell's area) when you sign up for service.
