The voip market is wide open at the moment. The big players are Skype and Gizmo and GoogleTalk. In general I like the Gizmo Windows-client the most, it's really neat. At the moment the Skype client is the best one for linux. However in the distant future what I would like to see in linux is a merge/crossover between Gaim, PhoneGaim, Gizmo and GnomeMeeting, all in one app. I believe that would make a very useful im/voip(sip+iax+skype)/h323 app.

But there is also another option at this moment. In Windows there is a client called VoipBuster. It's like the others (sip compatible I believe), a bit uglier and simpler, but it has one advantage: At the moment it let's you make free calls out to landlines to most European countries (yes even Belgium for once!!) and the USA and some more nations. Therefore I think it's a good idea to use this client at the moment. As a new user you can only call for one minute, however you can pay 1 euro (which will remain on your account, just for security/abuse reasons) and then you can forever make free calls with infinite length. Well, at least in theory. We should be suspicious here a bit, because we don't know for how long it will remain this way.

This guide is about using the Kiax linux client (qt, but not necessarily kde) to take advantage of the VoipBuster network (which is iax based): http://david.dw-perspective.org.uk/VoipBuster-Linux-MacOS-Solaris-FreeBSD.html Follow this and you will be able to do the same as in Windows!

Kiax is a rather bad client, but it will just do. It's in portage as well. You might also want to read this forum post: https://forums.gentoo.org/viewtopic-t-375310-highlight-kiax.html

There is plenty of room for discussion on what settings give the best audio quality for a given bandwidth, so any comments on this would be welcome. The same goes for user experiences/ratings.

By the way, this is a one-time deal in that way that I won't make any updates to this tip. It's expiration date is probably a year from now or so therefore.

Greetz from Belgium,

Here is a good page to start from (on the topic of codecs): http://www.voip-info.org/tiki-index.php?page=Codecs
Personally I find Ulaw has the best quality. You should leave off the echo cancellation btw! Gsm was also giving me exactly what I expected - guess what !?- gsm quality. So I would use this one if I was on a thinner line. iLBC seemed the same as Gsm, but it's patented. Speex looked interesting on first sight but it really disappointed me because it had a big latency for me. As a conclusion I'll probably be using Ulaw unless bandwidth forces me otherwise.

I haven't tried, but if kiax can register, I don't see why asterisk couldn't :) (then i could dial out on my regular phone instead of some headset er whatever)

Edit

Just noticed the "run from windows once" thing (can't sign up from the website :( )

But, yeah, I'm pretty sure this would be easy w/ asterisk since it's obviously connecting to an asterisk server.

you could add an extension like _001NXXNXXXXXX that sends calls through voipbuster if they start with 001.

I'm trying to use voipbuster in wine, but i can't install it. When i have to enter the installation folder, the setup program tells me the path i entered is not valid. Every time, whatever i try.

If someone has been able to do this, i'd be very glad to know how. I'll keep trying; when i manage to do it i'll tell you. (if i ever manage to do it) :D

edit: elvisthedj, i liked the video in your signature (this is off topic, sorry)
edit2: possibly, it won't ever work in wine, but the kiax solution seems to be neat. Thank you, pjv!!!

Wine doesn't work as it says in the guide:
Quote:
The current Windows binary doesn't work under the latest Wine (at 24th May 2005). So don't try! However, I have received a report that it does work with CrossOver Office 4.2 - at least as far as the point where you create your username and password.

However VoipBuster say that they are working on a linux client (like everybody these days).

No problem, it's not my idea anyway ;-) ...

Are you still able to log in with iax.voipbuster.com?
I can't. I double-checked my settings, but it doesn't work with kiax.

http://www.madaphone.sk/ gives 6 mins free calls to Belgium, Denmark, Ireland, Austria, Finland, Spain, Czech Republic, Australia and UK - it's limited promotion though.

Pages are only in slovak, but simple:

first register at http://www.madaphone.sk/?id=registracia - order of fields - login name, password, name, surmame, street, town, zip code, email.

After some time u'll receive confirmation email.

IAX is viop.madaphone.sk. Working fine with kiax. enjoy ;)

Too bad for all of you that didn't try this yet! The free deal seems to be partly over. Some countries are still free, but a lot have changed from free to paying. Belgium unfortunately is one of them. Also you now have to deposit 5 euros.

Has anyone here tried http://www.voipstunt.com/ yet? They are somehow connected with voipbuster, but still have free phone calls to a lot of countries: http://www.voipstunt.com/en/rates.html - connection details are here http://www.voip-info.org/wiki/view/VoipStunt.

Stop posting hyperlinks to Free VoIP that do not have Linux clients....

Its a waste of bandwidth

I haven't had time to try VoipStunt yet but I think it's just SIP. There are plenty of SIP clients for linux. So once you have registered through the VoipStunt client you can use linux-clients. Ofcourse it would be better if it was 100% linux...

I have an USB phone, and tried using (i think) all Linux clients for voipbuster, most do connect to the service, but the problem lies with my hardware.

I have an USB telephone handset, thats really an USB soudcard, with speaksers builtin - in a telephone horn shape (Profoon IP-10). The USB telephone uses an C-Media soundchip, that Linux supports with its default usb sound driver. So far no problem. I can even make XMMS play MP3's through it. ;-)

The driver only supports opening the device at 44100hz/16bit/stereo - other frequencies are not possible, if you want to use something else, the software and/or driver should do the up-/down sampling. The Linux voip applications all try to open the device at 9000hz/something. So with all Linux applications (Kiax too) - I get an IOCTL error on stderr, stating that the device does not support the sampling rate. One application just ignored the error, opened the device, and all you would hear is a ticking/crackling sound if someone spoke to you - no words recogniseable. The other side could hear me fine.

I also noted that most Linux voip apps make use of libaudiofile. So all apps compiled using libaudiofile, dont work per definition. I also reported this on sourceforge to the kiax devs, but no fix to this day, and I'm not good at C programming (I tried hacking the source, but no success).

So I had to get back to XP, just to use the voipbuster service with my telephone set (and for that matter, any VOIP telephone apps) - OR go back wearing that stupid headset thing, wich is also not an option. I chose the first, although I'd rather use the Linux PC for voip, simply because its always running and online. Now I have to boot a XP PC, to make a phonecall.

So far my adventures in VOIP on PC land.

Try to play with your mixer setup in ~/.asoundrc (see the alsa config docs). There might be a way to make a mixer that up/downsamples automatically.

No idea what to do about libaudiofile.

I tried making an asoundrc that does up-/downsampling, I spent about three evenings on it, and managed to do nothing. The documentation on asoundrc is very unclear (I cant understand what they're talking about - im not an audiophile) and questions here in the Gentoo forum got me no replies. If someone could give me a pointer how to make a simple audio /dev/dspxx device with asoundrc, that takes 9000hz input, and upsamples it to 44100 - i'd be very very grateful.

The libaudiofile apps (Kiax and friends) "dont work per definition" because of the instant application exit when the device cannot be opened at the frequency it demands. libaudiofile and the apps as such install and start fine, thats not what i meant, lets be clear about that. It all works fine, until the audio device is opened.

Now also internetcalls.com. Mmmmh, the more I see of these companies the less I trust them. Especially if their sites look identical.

Voipbuster, and I suppose voipstunt as well, now use sip instead of iax, which makes the successor to gnomemeeting, ekiga (ebuild on bugzilla), an excelent app to use the service. I find it much less troublesome than kiax. It does alsa by default. No more need for windows. Having said that, I often find the qualit of voipbuster quiet lacking. Could be roommates eating all the bandwith though. But skype is much better on quality.

I was wondering how they can offer calls for free and finally found some background information:
http://doulos.wordpress.com/technical-information/finarea/

Well, doesn't sound as naughty as I expected, though I wonder why they are so anxious about having us installed their windows software (for registration only):
http://www.sipdiscount.com/en/register.html

Even if I had windows running on any of my machines I would never ever install a program which is obviously of no other use than installing some sort of spyware, adware or other kind of malware (of course they claim that is doesn't do that but what else could it be good for?). Would be the first company incapable providing a registration form on their website.
