Exchange names derived from many sources, some local landmarks, but others randomly. When dial came along some renaming was necessary, as MAin would conflict with MArket (unless it was seven digit, and in many places it was six digit, eg MAin 1234). For some reason, the Bell System renamed some exchange names that referred to the town. For example, Elizabeth NJ had ELizabeth, but that was changed to another name (FL), same dial pull. Why, I don't know.

That's very much up to how Concentric sets things up. I'm assuming that you're using SIP for VoIP connectivity. I think that in a setup of this sort, you would probably want to have separate SIP "credentials" for the two SIP client (the SPA at home, and the Bria softphone), both tied to the same CallCentric account, so that both could register with CallCentric at the same time. Many but not all SIP providers support multiple credentials / clients per account. You would then configure your incoming DID line at CallCentric to ring one, or both of these clients (assuming that they're active) when an incoming call arrives. It looks as if CallCentric will allow you to do a simultaneous ring of up to three separate destinations. If you have both clients run, the commonest situation in the SIP world would be that the first one to answer would get the call, and the ringing call to the second client would be cancelled as soon as the first client picked up. There would be no "party line", no "3-way calling" in this situation. SIP-based VoIP systems certainly can support 3- or multi-way calling, but it involves a more complex call-setup system, and some audio-mixing software running at the VoIP provider's system. CallCentric does support it (up to 4 parties) but it requires manual action to set it up (e.g. your home phone would have to flash the hook and then initiate a call to the Bria) and it looks as if it costs additional for each call (e.g. the call to link in the Bria would be billed as a separate pay-per-minute call). -- Dave Platt <dplatt@radagast.org> AE6EO Friends of Jade Warrior home page: http://www.radagast.org/jade-warrior I do not wish to receive unsolicited commercial email, and I will boycott any company which has the gall to send me such ads!

The authoritative answer to this question involves the cross-mating of a rhinoceros and an elephant.{1} The best way to get a rational answer to this kind of query is to ASK THE MAKER of the systems involved. To find out how CallCentric deals with such things, *A*S*K* *CallCentric*. To find out what 'Bria" does, ask 'whomever it is' that makes/sells it.

He means good prompts are "for Foo, press 1." Not "Press 1 for foo". I know I want foo, or am at least likely to decide that's what I want when I hear it as an option, so all I have to do is listen for press 1. If you tell my which button to push, I have to remember that and listen to the explanation at the same time. That's annoying. It's worse if there's more instruction than that. A company I deal with from time to time has an instruction "Hang up, and dial 800-xxx-xxxx if this is an emergency". (It's worse, because one of their prompts dials that number for you.) -- sig 47

Making 'marketing' calls to a cell phone, or to a residential number on the Federal "Do Not Call" list, is prohibited by Federal statute. 47 USC 227. (Aside, the FCC and/or FTC will take action, if they get enough 'legally admissible' -- i.e. where the caller can be reliably identified -- complaints to warrant it.) For a private lawsuit, 'statutory' damages are a minimum of $500 _per_call_. If you can convince the Judge that it was a 'willful' violation -- 'spoofed' caller-ID makes that a slam-dunk :) -- the statute provides for trebling the damages award. So you have a potential $1,500 award per_call made. [Note: in virtually all jurisdictions, neither side is allowed to use a lawyer during the trial.] A 'small-claims' filing is "petty cash". IF they are legally doing business in the state, they are required to have an 'in state' agent for legal purposes. This is on file with the Secretary of State in each state. (Note: if they're -not- on file there, the SoS office is likely to be 'interested' because such 'failure to register' =is= a violation of State law.) You probably =would= have to file in the county where said agent is located. The 'real fun' for a small-claims action could be in "discovery" -- asking them to produce records of 'all similar calls' made for some 'reasonable' (say, 'last three years') time period, and evidence of what tests they made to prevent calling proscribed numbers. A pattern of proscribed calls would be near-compelling evidence for a treble-damages award. Not to mention fodder for a 'real court' "class action" suit >>> In Great Britain, dialling 14258** after an unwanted call bars it; this >>> seems to work even after a mobile call; do you have such a thing in the >>> States? > >> Some telcos offer a service like that, for a limited (and *small*) number >> of numbers, as an extra-cost (as in 'pay every month for the privilege of >> being able to do it') service. > >But at least in California, the service has limitations that make it useless: >(1) The number to be blocked must be within your local service area (LATA); > they won't allow blocking of other numbers even if caller-ID shows them. >(2) Blocked callers can still get you by calling the Operator.

But even that is futile, because spoofing is easy. There are commercially available devices that let you do exactly that, and more. e.g. dump 'known bad' callers, pass 'known good' callers through, and handle 'unknown' callers with any of several sorts of 'challenges', before ringing the 'protected' phone(s). >Indeed, this security blog reveals that spoofing is openly offered as a >service you can buy over the internet: >http://feedproxy.google.com/~r/KrebsOnSecurity/~3/aum_M7_LTtc/ > >So unless we can get the police to prosecute the likes of spooftel.com, >there's no hope. IF somebody uses a service like that for criminal use -- e.g. harassment, threats, stalking, etc. -- then, in addition to prosecuting the actual caller, the service could be prosecuted for 'aiding and abetting' the crime, or, possibly, "accessory before the fact". That said, not all uses of such a service are criminal. This makes it -very- difficult to legislate such services out of business.

It sounds like the key ingredients are: - Stringing along the caller until they reveal enough information to positively identify them - Somehow convincing a judge that I really did carry on the conversation I'm citing. The ones I've tried to string along so far seem to have the evasion thing down pretty well. They keep wanting to know more things about me but don't reveal anything about them (as in where they are located and/or their phone number).... and tend to terminate the call when I lean too hard. -- PeteCresswell
