Ask most people about internet telephony and they’ll probably think of Skype. After all, it’s the most popular service of this kind in the world and available of a wide range of devices. But Skype isn’t the only internet telephony service out there; far from it! In fact, there are thousands of services all over the world using open standards that provide the ability to make and receive phone calls over the internet.
No matter which service you choose to go with, you’re going to need an app to actually make and receive calls. Telephone, as you may have already guessed, is a VoIP client that provides this functionality. I put the app through it’s paces and see if it really does what its name suggests.
