SPA 3102 - Totaly Stuck!

Discussion in 'UK VOIP' started by Port Admiral Haynes, Mar 9, 2007.

  1. I have just received my SPA 3102 and trying to get it to register with
    VoipDiscount and failing.

    I do not want to use the router part of it so I have used the instructions

    And logged into it.

    I have gone to the Line 1 tab and entered my VoipDiscount settings as per
    their page.

    It fails to register. Any suggestions?

    Have you, by any chance, given the SPA a static IP address on your local

    Have you disabled DHCP? This will also break DNS. If so, just enter your
    ISP's DNS server IP addresses - On my SPA21xx, these settings are on the
    WAN setup page of the Router side, below Optional Settings.

    I advise:-:
    DHCP : no
    Static IP: Whatever you decide ...something like
    Gateway: same IP as that of your router eg.
    (just have to make sure that the static IP you pick is within the
    range specified within the router settings.

    That way you will always know what address to type into your browser
    to access your ATA (i.e. the static IP address of your ATA)

    You should also look at setting DMZ in your router pointing to the
    static address of your ATA (see above).
    An alternative to setting DMZ is to forward all the necessary ports.

    A further thing you could do is set a STUNserver entry (on SIP tab of
    my SPA-3000)
    Something like
    STUN enable:Yes

    After doing all that you'll have to be very unlucky for it not to
    work :)
    It shouldn't matter which STUN server you use.

    If you are using a static IP *make sure* you have put a working DNS
    server address in or you will not get anywhere. Plus you want to use an
    IP address that isn't in the DHCP range set on the router (but obviously
    in the same subnet) or the router could go and assign the same address
    to another device on your network which is bad!

  5. Still no go! Can I explain what I have done so far so you can tell me where
    I am going wrong. I got the SAP 3102 after suggestions from this group. I am
    happy with my current router so do not want to use the 3102 as a router just
    as an ATA.

    I accessed the voice menu via the phone connected to it and did a factory
    reset, enabled fixed the fixed IP address of and enabled the
    WAN web server.

    I then plugged a network cable from my switch into the blue port (labelled
    Internet) and accessed the Web Server by using the fixed IP address. If I
    plug the cable into the yellow port (Labelled Ethernet) the status lights
    flashes and I cannot log onto the WAN Web server.

    After logging on I go to WAN setup and type in the network mask, gateway and
    DNS addresses.

    I then got to Line 1 and enter my voipdiscount details.

    Do I need to touch the LAN settings. I have turned DHCP off here - it seems
    to have a fixed IP address of

    Any suggestions - many thanks for your help.

    There are a lot more ports than that.
    I'd set the DMZ up first then, once you have got tha ATA to work you
    can think about port forwarding.

    Yes, one thing raised by Paul was the DNS server.
    If you are using a static IP you can set the ATA so that
    the primary DNS is equal to the same IP as your router.
    So, you will have both the gateway AND the primary DNS set to the
    same IP as the router IP. That works for me with the SPA-3000.

    If you are not using the ATA as a router these are the only
    connections you should need to the ATA:-
    1. Power supply
    2. telephone handsets
    3. landline (if you have one)
    4. One connection from your router to the ATA.
    Presumablyly it is possible to switch off the router part of the ATA -
    I don't know about this, I've not read it up, so someone who has one
    would be best to advise.

  9. Right its working!

    In the WAN setup I turned on DCHP - it then picked up an IP address from the
    router and work fine. No port forwarding or DMZ needed. Slight drawback is
    that I need to use the Voice Menu to check the IP address if it changes

    Now I can dial out using VoipDiscount.

    Now the next problem - what do I put in the PSTN line settings - I have a BT
    landline I want to connect to it

    Yes, that is exactly why it is best to use a staic IP. You do need to
    have DHCP set to 'on' in your router but not in your ATA.
    If you set it on oin your router then set a static IP as I have shown
    previously it should work OK.
    It will be a real pain having to call up your ATA to find the IP and
    then typing it into the browser every time you want to adjust
    settings. Far better to use a static IP.
    Answered in your separate post.

    Download a program called
    It will enable you to keep your current settings so that you can muck
    about with them and, if you want, return to the previous settings.
    Do check though that it has properly saved the data. Sometimes it is
    necessary to close the program and re drag the data you'll get the
    idea when you've tried it out.
