    I'm new at this, so if anyone could provide a little information that
    would be great.

    I'd like to use my cordless phone to place voip calls so I know I need a
    ATA analogue telephone adapter. I'd like to plug the ATA into my Dlink
    router via an ethernet RJ45 port so I don't need the computer running in
    order to place a call. It also means other family members are not tied
    down to my computer as with USB/Headset software solutions.

    The thing is, can I then make a P2P call to another voip user if I don't
    have a provider? Must I absolutely have a provider if I don't want to
    use a software solution or a USB solution?

    The easiest way to make free calls to other people using your ATA or other
    SIP-compliant VoIP gear is to sign up for a number at Free World Dialup

    Or if you want a UK number (you do need to use a British
    based IP address if you want a normal geographic number in the UK though,
    but it can be used from anywhere).

    Not a Problem thats what most people do.
    Well the answer to this is a yes / no on one.
    Put simply yes you could make P2P calls without a Voip Provider, BUT
    why would you want to, Firstly it will make it dificult for people to
    call you, and you wont be able to get the benifits of reduced cost
    toll and International voip to pstn calls. Most SIP suppliers dont
    charge any "line Rental" just charge for off net calls, look for
    suppliers that have good peering to other voip providers.

    Thanks for the replies. I guess I'm having trouble visualising how it
    all fits together. For instance,

    do I need an ATA adapter which is specific or constructed by a
    particular provider? If not, how does the ATA which is plugged into my
    router know the ip of the provider or where to send the data?

    If I don't have a provider, how can I then make a P2P call to another
    voip user? The ATA is just a digitizing device and knows nothing else..?

    Does it matter where the provider is located? I'm in New Zealand...

    Thanks again.

    It has to be compatible with their software and protocols, but that usually
    gives you a lot of options.
    If the provider sends you an ATA, it will come pre-configured. Otherwise you
    have to configure it (using a web-based or phone-based interface) with
    settings they give you.
    Yes, you'll have to dial by IP address in that case. And if they are behind
    NAT (e.g., a home router) then it probably won't work unless they have made
    special arrangements on their router. In this case you are better off using
    FWD as I mentioned earlier in the thread. It's free and easy.
    If the provider is far away from you then there can be noticeable latency.

    For instance, I live in Malaysia but buy SIP minutes from a provider in the
    USA. For calls to the USA and Europe, and even Japan and Australia, this is
    no problem. However, when I call back to countries near me (such as
    Thailand, or Malaysia itself) the delay is quite perceptible because the
    information is traveling twice around the world over apparently high-latency

    So even though calls from Malaysia to Malaysia using VoIP via the USA are
    cheaper than calls directly dialed from my Malaysian phone, I still end up
    direct-dialing because the delay is so annoying.

    Oh, and if I may, what ATA should I be looking at for the straighfoward
    RJ45 setup I have in mind? Where can I find such a thing as there don't
    appear to be any availabe in NZ.

    The ATA has the info programmed into it.
    No The ATA is the device that will let you make the call
    No realy The important thing is latancy, So if you intend to call
    people mainly in NZ use an NZ supplier , But for example if you are
    going to use it to contact people in the UK use a UK supplier get a UK
    number and that way they call you on a UK number IF they dont have
    voip and you can call them at local rate if they dont have voip or you
    do a P2P call

    Have a google the are some very good voip companies in NZ are down south in Dunedin for example.
