The AT&T COCOT which I was referring to, for example, blocks the call after you dial10X. It won't even let you complete the last 2 digits of the equal access code, before it cuts the caller off, immediately, and says "That is not a valid number. Please hang up and try again". It does the same with 950 calls, so in effect one must use the AOS the COCOT is programmed to call. - AT&T COCOTs, and most other COCOTs, are quite programmable, and let you program things from access numbers to block out to how long the Touch Tones are, etc. One recent COCOT which I found which was borken allowed me to set the access code to the COCOT to something new, so that in effect only I can program it now. (The code used to be 1234, which I just happend to dial when playing with it, and to my surprise, ti worked!) - Most COCOT lines don't go blocking out lots of services. Indeed, in New York and New Jersey, at least, COCOT lines onlt block out 0-700 calls (basically AT&T Alliance, which most COCOTS let through...). All other services, including 900, 550, 540, 970, 976 and international dialing are all allowed, although it's possible that a COCOT owner may ask the local Bell Co. to block calls for these as well. (I'm not sure if Bell will block calls on a COCOT line). A COCOT line also indicates to the local Bell operator that it is a COCOT line, so she can be REALLY rude to the customer using it! ;-) - In short, although it should be possible to block out 10xxx and other calls from the local switch, it seems that generally COCOTs are quite programmable (unfortunately!) and do a very good job of blocking all by themselves...! - Thanks again for writing back to me... -Doug - usereafj@rpitsmts.bitnet (temp.) - re: Don Ritchey / dritchey@ihlpl.att.com telecom@xx.lcs.mit.edu
