    You know the sort of thing. Allows you to call Skype contacts using your
    standard home phone. Anyone know one of these that works with Windows 7 as
    well as XP? Thanks.

  2. I am using one of the D-Link DPH-50U devices on my Windows 7 Pro-32bit
    system and have used it just fine on my older XP system with no problems.

    The drivers that come on the CD were not W7 compatible but after
    downloading Version 1.1 (Vista) drivers the device worked just fine on
    my W7 system.

    The drivers on the CD worked just fine with my older XP system.

    I did notice that the US and UK D-Link support sections have different
    versions of drivers with the UK dated 2006 while the US support section
    had 2007. Just thought I'd mention this in case the UK version does not
    work on your W7 system.

    According to the US support site the device will no longer be supported
    by D-Link after August of 2010 but I still find them widely available on
    the internet new as well as used.

    How times have changed, a couple of years ago asking a question about
    Skype on this NG would have brought howls of displeasure

    Used to be if it ain't SIP it ain't VOIP

    Well, if the number of answers a post receives is a sign of the interest
    it receives, posts with "Skype" in the subject sometimes don't even
    receive the consideration of ONE answer here.
    I'm left without the will to live when somebody with a Skype question
    pops in here... Like if somebody with a question about the price of a
    spare for his car writes to the Ministry for Transport. UH???
    Doesn't Skype itself provide support for the devices that adopt their
    buggy, sneaky and proprietary protocol?
    It's a proprietary application, with a proprietary protocol, and an
    owner with a website and a customer service.
    Just effin' go there, do us a favour.

    When I wrote the introduction to
    I felt the need to almost apologize for using Skype for those very same reasons,
    but that doesn't change the fact that being able to make a call through a SIP
    gateway, from a PAYG mobile phone with no network credit, is extremely useful.

    It was a means to an end :)

    That's how i see Skype, if i didn't have a Three network S2 phone with free
    Skype i wouldn't bother.

    Not when there's services as cheap as

    Your SIS to SIP conversion is an ingenious use of Skype.

    Well I didn't write siptosis on which it is based. All I wish to do is encourage is taking
    full advantage of 3's kind offer of "free calls forever" promise.

    I'm sure that's what they want ;-)

    OK Graham I see you use anti spam <>

    Please email me at my addy in the header (change four to 4),
    i have some ideas about cheap 3 calls i can't talk about on here.

    Thanks for that. I saw that one on my web search! I noticed that Trust do
    one too but they don't seem to have Win7 drivers available.

    Well I am looking into those too ;-) It's just that my family all use Skype
    so it's a good place to start.

    The trouble is that Skype is a worldwide system offering calls from
    any subscriber to any other subscriber for free, for ever. The SIP
    service providers are fragmented and won't talk to each other for
    free; it's far worse now that when I signed up for Sipgate a few
    years ago. All the SIP providers want to make money from us like
    traditional telecoms companies do. They're killing SIP with their
    greed, not entirely unlike what BT did to ISDN - although of course
    BT did it alone.

    Meanwhile, at the uk.telecom.voip Job Justification Hearings, Dave Higton
    chose the tried and tested strategy of:
    How else are they going to pay for power, colocation, bandwidth, etc? Fairy
    dust? I very much doubt the pure-SIP operations like Sipgate are raking it
    You are at liberty to put a SIP server on the internet and not charge
    anybody to use it.
    Someone must have forgotten to tell the phone systems I look after about the
    death of SIP and ISDN - all of them use ISDN, some use both.
    alexd, Jun 26, 2010
  13. Both SIP and Skype require some sort of registration service and a
    3rd party to relay audio data through when both endpoints are behind
    NAT. Skype provides this for free by utilising the good-will (or
    ignorance) of 3rd partys that they (Skype) have no direct control over
    - these "supernodes" are ordinary people who are deemed to have good
    connectivity... In the SIP world, these servers are hosted and managed
    by people/companies and someone somewhere needs to pay for them.

    Most SIP service providers act to bridge calls to & from the PSTN -
    and that is an area where money does need to be exchanged - so that's
    no different from SkypeIn/Out.

    So I don't think you're right when you say that we're killing SIP with
    our greed - the simple facts are that the primary reason for commercial
    SIP providers is to provide PSTN bridging and to do this we need to host
    servers and pay for bandwdith, and the PSTN interconnect fees.

    And there is nothing on the planet (short of technical inability and
    hurdles such as firewalls) stopping you from doing a direct SIP to SIP
    call between you and your mates. Go ahead, register your numbers with
    an eNum service and off you go.

    Compare with Skype: universal, free to everybody. If you're an
    unskilled punter, which are you going to choose?

    Where do they get their fairy dust from?
    Like SIP VoIP, it's not dead, but it didn't take over from analogue
    lines to nearly the same extent in the UK (where BT priced it with
    a stiff premium) as in e.g. Germany (where it was priced the same
    as analogue and known to be much better).

    In case it's not clear to you, I'm talking about the choice perceived
    by, and the services chosen by, unskilled punters.

    So: how many other VoIP service providers do you peer with for no
    cost per call?

    Dave Higton, Jun 26, 2010
  16. There is nothing in SIP that requires you to use a third party provider,
    unless you want to make or accept calls from the PSTN, or register into
    a phone number type address space. Skype charges for outgoing PSTN
    calls and, I believe, there are people who provide incoming SIP gateway
    services on revenue sharing basis, like Skype do.

    SIP phones are probably designed for corporate use, and therefore don't
    make pure SIP point to point calls easy.

    Meanwhile, at the uk.telecom.voip Job Justification Hearings, Dave Higton
    chose the tried and tested strategy of:
    Skype, obviously, because it's better. More people are on it and it's easier
    to use than SIP.
    a) They have paying subscribers - $185M revenue Q3 2009.
    b) See Gordon's post.
    c) eBay poured a not-insignificant amount of money into Skype.
    d) They sell hardware.

    Future sources of fairy dust include:

    e) Advertising for non-paying users.

    They've got a great brand, a massive 'network effect' around their product
    and they've got lots of room to start squeezing money out of people who
    don't pay them anything yet.

    However, Google are offering competing services so Skype can only squeeze so
    hard before people realise there's an alternative. I wouldn't be surprised
    to see Google set up some sort of Skype-Google Talk gateway in the name of
    interoperability, and before you know it, Skype's major advantages begin to
    fade away.
    Who cares? ISDN may be technically better than POTS, but the more
    appropriate product won.
    alexd, Jun 27, 2010
  18. Exactly the same number of other VoIP providers that Skype peers with
    for no cost per call.

    The few SIP phones and ATAs that I have come across and used do seem to
    allow calling to specific IP addresses. However, it seems to me that
    the expectation of a SIP phone/ATA is that it will talk to a SIP server
    that will take the dialed number and map that to an appropriate target
    (real phone network, internal extension number, other SIP provider,
    IP address, or whatever).

    In my case, my SIP ATA registers to Sipgate but makes most of its calls
    out through a Betamax provider. (At the moment I have no need to run my
    own SIP server, so I don't.)

    Chris Davies, Jun 28, 2010
  20. What also doesn't make it easy is NAT - if you've got 2 SIP phones behind
    NAT, you'll need to use port-forwarding at each end to make it work -
    and that's just for one phone - for a 2nd phone, it get's harder as you
    have to make sure the 2nd phone uses a different port... and so on.

    NAT introduces many other complications too - which is why an external
    registrar and media proxy makes like much easier. (In the same way a
    Skype supernode makes some NATted connections possible)
    Some (e.g. Snom) will allow you to dial a URL,
    e.g. sip: but you need to connect to the
    phones internal web interface to do this (dialling a URL on a phone
    keypad is tricky unless you're a TXT junkie!)

    And the recieving system needs to be able to accept un-authenticated
    calls from sources where you can not trust the caller ID.

    Imagine if call centres could call you for free using computers...
