Re: [Asterisk-Users] No Caller Name sent from Asterisk over Nationalor DMS100 PRI to a Norstar MICS?

But how? As I understand it, the scenario you described is already how things work. LECs and CLECs do not manage their own Caller ID databases (at least not for other telcos to dip into), all of this data is stored in the nationwide SS7 network, managed by VeriSign (used to be Illuminet). When a telco switch receives a call from _anywhere_ and it wants to deliver Calling Name to the called part, it does an SS7 lookup to get the registered Calling Name for Calling Party Number that was given to it. It _is_ possible for the caller-provided Calling Party Name to be transferred all the way across the network and delivered to the recipient (if both ends are ISDN-equipped), but this is not common, and is a major security (such as it is) hole anyway. So, to answer your question: whichever telco is currently providing inbound service for a given DN (and billing the customer for that) is responsible for maintaining the associated name record in the nationwide SS7 network database. If the customer is able to generate calls using another telco and provide this DN as the Calling Party Number, the called party will still see the same Calling Party Name, regardless of the originating telco for that call or the path it took through the PSTN. ___ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

The owner of the connection to the PSTN (Telco) must insert the NAME portion for Call Display. There is no way around that since its their database the NAME is located in. Someone correct me if I am wrong . Brandon For instance, it is possible to set your Caller ID Number on an outbound PRI call to 202-456-1414; on the callee's caller ID Display, the name and number will read THE WHITE HOUSE 202-456-1414. However, I do not recommend doing this. It is just a colorful example. ___ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

Someone correct me if I am wrong . Yes, I think it's fair to say that the ILEC/CLEC to whom the phone number is routed is responsible for publishing reverse name lookup for that number. This is somewhat analogous to in.addr.arpa reverse lookup for DNS. It should be noted that, with LNP, any single phone number can be bound to any carrier, so there is not necessarily any notion of native numbers for a given carrier, etc. That all being said, does anyone have any experience with what databases/mechanisms CLEC's might use to maintain and disseminate these reverse lookups? I can think of some weird scenarios: A) 443-555-1212 is a published number for Consolidated Cheese Corp and is initially serviced by Verizon. B) Consolidated Cheese later ports 410-555-1212 to a facilities-based CLEC-provided PRI C) Consolidated Cheese signs up for a VoIP termination service and wants to set caller ID to 410-555-1212 for its PSTN-bound calls. The VoIP termination service is provided by a different CLEC from (B), possibly in a different geography. So, assuming CLEC in (B) has done its job and published some sort of reverse lookup for 410-555-1212, calls made via (C) should, in theory, correctly display Caller ID Name for the callee's. But how? The only way I can think of for this to work is for a dip to be made for the reverse lookup, presumably via a SS7 request, to the (B) CLEC, even though the call may not originate with, terminate on, or otherwise pass through (B)'s switch network. (B) would only be touched for the reverse name lookup. If this outline is close to reality, is there any notion of distributing these name lookups, a la DNS? What about caching/TTL? Where is this stuff written down? Comments?

If I recall correctly, the National ISDN protocol (NI2, I think) has the capability of forwarding CID NAME to the provider who can then do whatever they want with that information (including simply discard it).
