VoIP for free with the Sipura

by @ 15:48. Filed under
SPA3000 System menu

Step 4 – Not necessary but a nice to have

On the systems tab you can enter NTP server information. NTP stands for Network Time Protocol and what this means is that the Sipura will ask these servers for what time it is and use it for all things that needs a time stamp. For example if you look at the info tab then the you can see what time the SPA registered with a server last.

Fill in the information from the picture to the left and press Submit all changes.
You should also set the time zone which is done on the regional tab at the bottom. GMT +1 for central Europe, GMT for the UK, GMT -6 for EST, GMT -9 for PST. Then Submit all changes.

Step 5 – Done, let’s test it

Now, hold your breath! If you disconnected any cables earlier then plug them back in and pick up the phone. You should hear a dial tone.

Testing the regular phone line: Call a friend or your cell phone the regular way by just entering your number. Hopefully it should ring – pick up the phone. Ok, that worked and you can hear yourself. Now unplug the cable that is plugged into the SPA3000 Line plug. The phone call should now be disconnected as it was using the regular phone line. If it didn’t disconnect then the call was placed over VoIP.

Testing the VoIP line: Call a friend internationally. If the landline phone number is in the states then dial 001+areacode+phone number, in the UK 0044+areacode+phone number. You should hear the phone ringing and if your friend is home then he might even pick up. When the call is established unplug the Line cable from the Sipura. The call shouldn’t be disconnected as you are now calling over the Internet.

The only drawback I’ve been able to find with the Sipura SPA3000, and their other models as well, is that the documentation is very bad. It’s actually very detailed but a bit to detailed. Actually it’s so detailed that even though I have 17 years of experience within IT and electronics I have problems understanding what the h**k they’re trying to tell me in it.
Lucky for you and me this little box is very popular in the open source world and there is tons of websites you can go to for help. Here are some of them together with other interesting VoIP links.

Sipura system tray monitor– A little utility that sits in the system tray and monitors your Sipura. I use it myself.
Sipura SPA3000 – Overview over the Sipura series with technical documentation.
Linksys (Sipura) SPA Users Group –  A great forum for help with the Sipura. – All information you could ever ask for about VoIP.
Asterisk@Home – Asterisk, the free PBX (telephone switch), easily installable on one CD.
Asterisk for dumb me – An easy manual for Asterisk.

That’s about it. What you’ve read on the past couple of pages is what you need to now to get started. Sure, as most Sipura owners will tell you, there is tons more you can do, buy hey – this is what I want to achieve with it! Lift the phone off hook and just call without mumbo jumbo. And when the day comes and VoIPStunt stop existing then I jump on the next train that suits my needs. The SPA3000 will surley support it!

  1. Chip Schweiss Says:

    Be warned, the Sipura SPA-3000 has only a rudimenatary echo canceller. If your phone line has much echo you will have real problems using the SPA-3000.

    BTW, you probably never have noticed echo on your phone line because it is an electronic echo that travels on the phone line at the speed of light. Once you put any sort of delay such as an analog to digital conversion such as going to VoIP you will add anywhere from 10ms to 100ms of delay to that echo. If it is not completely cancelled you WILL hear your voice as you talk on the line at delay that can make talking very diffacult.

    All analog POTS lines have echo, some are worse than others. With devices like the SPA-3000 it’s a crap shoot if you will experience echo or not. I’ve used them in places with low echo on the line and they do work great. But in other places, they are complete junk for the job.

  2. Chris J. Says:

    Chip: That might be so, but I have only noticed this echo problem one out of ten times and then it’s so weak that I can barely notice it.
    What kind of device would solve this and what would it cost?

    The bottom line here is that for $100 + $10 I can call for free for four months to my friends in Sweden and the states. Write that off over two years and you get $6 per month, and for that kind of money I’ll accept a small echo every tenth call.
    In my opinion the Sipura rocks!! It sounds like talking in a regular phone.

  3. John Says:

    so where do you get one?

  4. Pasil Says:

    How do I use Sipura and skype so Ican call skype users without having my pc on
    all the time? Is it possible?

  5. Chris J. Says:

    Pasil: To my knowledge you can’t.
    What you could do is that you have one Sipura and so does your friend in Iran and then you call for free between the two Sipura’s. You could then configure the Sipura in Iran to connect to the telephone line there and then you can call for local prices in Iran from your Sipura.
    What this actually means is that you become your own VoIP provider 😉
    How to do this you can read here

  6. Dimitrios Says:

    I have a small and not yet profitable enterprise and I want to use a software instead for a hardware PBX.
    I shall be much obliged if you are kind enough to help me find the cheepest solution.
    Many thanks in advance to consume your time in replying to my request.

  7. Chris J. Says:

    Dimitrios: If you want to use a software solution then VoIPStunt will still work for you as you can install this on your computer and use it together with a headset. Another solution is Skype which is more popular but not as cheap.

    Where do you call from and where do you want to call?

  8. Mark Says:

    Dimitrios –

    This may help you with what you are looking for.
    Product from VoSky. I use the VoSky Internet Phone Wizard with Skype and it works great.
    Good luck.

  9. Frank Says:

    will Sipura SPA-1001 (about $60 from ebay) or Grandstream HandyTone ATA-286 work with Voipstunt as well?

  10. Jim Stainton Says:

    I have an SPA300 and would like to be able to configure it so that I can use the FXO port to forward my home phone (PSTN) to a soft phone [I am looking at Counterpaths X-Pro or X-Lite]. without using a service provider
    – How do I configure the SPA3000
    – How do I configure a soft phone
    – Other issues – NAT etc?
    I am new to Voip.

  11. george007 Says:

    the following adapter works with voipstunt,

    But if the usb adapter with call forwarding functionality could support voipstunt, it would be great.

  12. sm Says:

    is it possible to convert an analogue phone to ethernet and have some sort of software forwarding skype to an ip address?
    (ethernet as in connect it to a router)

    would preffer an email, thanks in advance


  13. CMP Says:

    Hey, thanks for the awesome “for idiots” guide… spent 4 hours playing with the stupid thing, and after going through your guide i finally get it lol 😛

    thanks again

  14. Mike Says:

    SKYPE sucks. They are stuck on the idea of navigating against the waves. 90% of the present market are using the SIP protocol, but skype uses a proprietary protocol and will sink attached to it.

  15. Mike Says:

    SPA3000 is good like hell! First you can have two VOIP systems attached to it. Let’s say, you live in Spain but have friends in UK and Germany. So, you subscribe free to, in England and receive a free real UK telephone number and subscribe free to and chooses a free real Germany telephone number. Now you have 3 phone numbers, in 3 countries. Your friends from germany can dial to that phone in germany, paying local call and your friends in the UK can call you using that phone number in the UK paying local calls.

    Of course, you can talk in conference with one person in UK and one in Germany, using SIPURA SPA3000.

    You can do hell. Imagine you want to forward all your calls coming to your UK number, to a number of a friend in Germany. So, anytime the UK number receives a call, it cames to your box in spain and is forward to germany, just paying a local call in germany.

    Imagine you are in germany and want to call your friend in the UK using your box in spain…. or you are in Brazil, using a laptop and want to call your box in spain, using the web to make a call to your friend in a mobile phone in the UK, paying a local call in the UK…

    possibilities are endless…

    SPA3000 is not just a voip box, it is what is called a GATEWAY, that can handle 3 simultaneous calls: 2 from web and 1 from regular phone…. and can forward from one to another at the same time…

  16. Peter Diez Says:

    I have voipstunt, got the linksys phone adaptor.
    This site rocks, did what it said on page 3, onlie making calls in seconds.

  17. Kransome Says:

  19. jimmyjimmyjimmyjimmyjimmy Says:

  23. Daniel Says:

    Is It possible to call a softphone from Sipura? How can I make It?

  24. Chris J. Says:

    Daniel: I believe so. If I remember right then you need to program the IP of that softphone as a quick dial number, but I’m sure there are ‘direct’ ways also.

  31. leonil7 Says:

    get the bundled PhoneGnome. give 1 to your friend, keep one to you. connect phonegnome adaptor to broadband internet, and to any analog telephone. then start calling each other for free as long as you want, just like new lovers!


    Phonegnome is simply Sipura simplified – if you want to avoid all those nasty configurations and just need to call.


  32. dhanusa Says:

    please tell me how can can i get the 60 minutes free phone calling

  33. Kartik Says:

    How can i Call to India Land Line / mobile numbers from Malaysia using Internet ..please let me know..

  34. Chasky Says:

    Hi.. technically, calls will never be free. For instance, you need to pay your ADSL
    connection or whatever internet connection you’re using. If you’re gonna make calls
    with a PSTN like hooked to your local company: you’ll –or your family abroad–
    be using the line so you’re paying to your local company.

    But… it makes you feel that it is free since you’re not getting any bill for international
    calls. I personally love my SPA-3000, I only use it to call my mother and my wife’s mother,
    and they call us. So I don’t need to have number in any other country.

    What I did was to sing in in FWD (Free World Dial up – in both
    SPA-3000, and I have “free” calls to my mother’s house, and very cheap calls to my wife’s
    house. They can even call us from a public phone (0.08USD for 3 minutes) by mean of the
    PSTN gateway to VoIP. It is just great.

    there could be some problems in the service some time… not that it is a big deal, usually
    it is a terrific service.

  35. dufster Says:

    I was wondering if you could help me figure out how to start a virtual service using you home number and some virtual extention
    using the spa 3000 as you may well know its impossible to get candian telephone numbers and i am trying to work my way around that
    because even skype cant get Canadian numbers or if there was cheap way of getting them canadian telephone numbers or virtual nos?
    Any ideas are welcome

  38. panzerboy Says:

    Hello Chris,

    I followed your tutorial but I cannot get it to work. I have the same issue as Giovanny (comment number 26), it tells me Registration state: failed. Any idea what can go wrong? Also, is there any way I can get any logs from the SPA3000 so that I can check where’s the problem?

  39. panzerboy Says:

    Ok, I figured out why it said registration failed by looking at the logs, it was because it couldn’t resolve the host (I don’t use DHCP and the DNS server field was empty). Now I can register, however, it still doesn’t work, it doesn’t even ring when I try to call somebody, it waits for, like, 10 seconds, then I get the busy tone.

    Any ideas?

  40. Kenneth Nilsson Says:

I have tried to understand SPA3000 , 9000 and Asterisk but …. Any advice?

  67. Oleg Says:

    Skype doesn’t use the SIP protocol to communicate over the internet, so it will not work with a SPA. You need to register with a provider that does, eg VoipStunt which is a twin of the other Betamax companies (, they are one of the cheapest out there. Remember that with Betamax, unless You buy credit, you will be able to make only short, 1 minute test calls to regular phones. is a great site which lists different providers, for both incomming and outgoing calls.

  68. Oleg Says:

    I forgot to mention the Voxilla forum (, it’s a good reading for someone new to VoIP and has users willing to help.

  69. Thasan Says:

    Hi Guys!

    I am Das from Dubai. Here all the voip services are blocked. But I can have access to the voip sites still. Is there any possibilities to call for free ( or atleast on cheaper rates to Sri Lanka.
