VoipWise

Born a "new" software for VoIP calls and free SMS sending very but very similar to the other ones I spoke about in an old little article.
Reading from the official site it seems that there's the way to make free calls over landline phones in the enabled countries:

Australia, Austria, Belgium, Canada, Chile, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Japan, Latvia, Liechtenstein, Luxembourg, Netherlands, New Zealand, Norway, Portugal, Singapore, Slovak Republic, Slovenia, South Korea, Spain, Sweden, Switzerland, Turkey, United Kingdom, United States (mobile phone included).

The sending of free SMS is limited, as calls over landline phones, it's not understandable in what manner it is, but... better that nothing.
VoipWise is freely distributed and it is translated in many languages, after the short installation it is necessary to sign up with classic username and password, the registration process is quite immediate and easy to do, after that it will be possible begin to use VoipWise, between the features it's present the Phone2Phone function, simply inserting your own telephone number and the one you wish to call, it will be estabilished a direct call between the two phones, without computer aid.
