Ok, I will give one final post on this. I had hoped that you would let it go seeing that I wasnt going to respond, but that was not the case. Here are a few examples of others that think they are indeed different: http://www.patentstorm.us/patents/7289613-description.html Unlike FG-D, which can only pass one call identifier, such as the caller's ANI, more advanced signaling systems can pass multiple call identifiers, e.g., the BTN and the ANI, which is helpful in keeping track of details used to bill telephone calls across telephone lines controlled by different entities. The patent indicates that they are separate. Metro One was the company that filed that. http://www22.verizon.com/wholesale/glossary/?l=b#billing_telephone_number Automatic Number Identification (ANI) The number transmitted through the network that identifies the calling party. Technically, a Common Channel Inter-office Signaling (CCIS) parameter that refers to the number transmitted on an out-of-band basis through the SS7 signaling network identifying the calling party's telephone number. Also known as Calling Party Number (CPN). Billing Telephone Number (BTN) The ten-digit number, including the area code, to which charges for a given telephone service are billed. Calling Party Number (CPN) The number transmitted through the network that identifies the calling party. Technically, a Common Channel Inter-office Signaling (CCIS) parameter that refers to the number transmitted on an out-of-band basis through the SS7 signaling network identifying the calling party's telephone number. Also known as Automatic Number Identification (ANI) If verizon thought the BTN was the same as ANI they probably would have used the same definition as they did for CPN/ANI. Further CPN/ANI make no mention of being the number service is billed to. This number has been known to traffic on the SS7 network as I had originally said, it however is almost never logged and if it were it would lead to the ITSP that interfced with the pstn and start allowing for tracking back to who actually placed the call. It takes at the minimum SS7 interconnection to specify this, so most people wont be spoofing that. I cited 2 reasonably large phone companies, and logically the reason why its different is because you may want all calls billed to 1 number but allow either arbitrary ANI setting to any of your multiple DIDs on that circuit. It is a separation between what will be presented to end users as the caller identity and who is getting billed. I hope that this can be dropped now and focus back on the original thread. -- Trixter http://www.0xdecafbad.com Bret McDanel Belfast +44 28 9099 6461 US +1 516 687 5200 http://www.trxtel.com the phone company that pays you! _______________________________________________ --Bandwidth and Colocation Provided by http://www.api-digital.com-- asterisk-biz mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-biz
