This blog’s first review is for VoipStunt, a client that’s compatible with the SIP protocol AND has free calls to landlines in 32 countries!

It’s not a pure softphone either, as it features a service called "directcall" (pictured) that calls your home phone first, waits for you to pick up, then dials the second number. This means that you don’t even really need a microphone, just an Internet connection.

As you can see, the user interface is standard, simple, and easy to use. It looks like a pretty blatant copy of Skype, which isn’t a bad thing.

When I signed up, there was no need to buy credits before calling. My first call went through immediately. The delay made it hard to have a great conversation, but the voice quality was good enough. I’d say it’s comparable to SkypeOut, but slightly less clear.

Unfortunately, there is a 30 minute cap on free calls. It hangs up and displays a message saying that you must purchase credits in order to remove this cap. You can call right back though.

VoipStunt belongs to a family of cheap VoIP clients, including InternetCalls, SIPdiscount, VoipBuster, VoipCheap, VoipDiscount, and FreeCall. According to voip-info.org, they’re operated by Finarea, a Swiss company, and/or Betamax, a German company.

After extensive testing, here are the pros and cons:

Pros: Free to many countries, direct calls, SIP compatible, nice user interface.

Cons: Delay, unstable voice quality, 30 minute limit.

Overall: 3.5 stars (out of 5)
