VoipStunt 4

It's available on the website www.voipstunt.com the download of version 4 of the famous VoIP software, VoipStunt.
I didn't find any changelog to find out bugfixes and possible new features, but after I installed it I noticed a new form that allow calls from phone to phone, like the way JaJah do, simply typing the sender's phone number and the consignee's phone number, always free calls in the countries specified on the VoipStunt website, and a new form for sending SMS.
I tried to send a few SMS and indeed they are been delivered immediately, but the maximum SMS allowed was five SMS, better than nothing seeing that they're free!
