betamax (voipbuster, voipcheap) - API for placing a call ?

Hello,

I am looking for some API that would allow me to initiate call with any betamax service.

Voipbuster provide an mobile Java applet for sending SMS or placing a call but I am a Voipcheap user and there is no such applet for Voipcheap. Eve, by decompiling, I have not been able to understand how it works.

So I would like to do my own WM app for Voipcheap (and potentially any Betamax service) for my HTC. Making it native for Windows Mobile would also allow to access directly to contacts database.

Unfortunately I didn't find any specification for such API (such as the SMS URL that is already published) while progx.ch as been able to find out how to do it...

Question can also be extended to the account balance which is also provided by Voipbuster Java applet...

Thanks for any pointer.

You can use the sip interface for establishing a call

Exactly - it's just SIP.

You can already get a SIP DLL kit for WM6, so 95% of what you want to do has already been done - you'll probably just need to tweak the installer.

The DLL kit cannot be used within the terms of the WM6 licence btw, so anyone using this would invalidate their warranty etc, but for your own experimental use it probably wouldn't present a problem.

Hi friends,

Just to be clear, I don't want to make a VoIP call over Data connection. I could use SJPhone for example for that. This is what I do over Wifi, but my 3G data plan does not allow me to do that.

What I would like to achieve, is to do same as the Java applet, PC application or Web Page : give my mobile phone number, give my destination mobile, then Voipcheap calls me back and once I have the line, it calls my destination and make the interco.

I can do similar things by sending a SMS to the special SMS call back number. But I believe that using an API (HTTP request or other) to trigger the call back would be faster (indeed it takes 30s-1min for the SMS callback to call me back) and easier to integrate into an Windows Mobile application that could connect to my contact data base.

I've been able to trace a little into Voipbuster Java applet and I finally found that it talks to a server called gsmproxy.voipbuster.com on port 9000 and that the protocol does not seems to complex.
Unfortunately this gateway seems to exist only at Voipbuster and not at Voipcheap...


So may be I am missing something with regards to your comment to use SIP. For me, SIP only allows to make VoIP call, with audio going through RTP on data connection. If SIP can do what I whant (triggering a call back + forward) then any pointer would be appreciated.

Thanks for your suggestion.
