Dan Ros and Sebastian Clarke will launch the Teleserver system later in the summer, which they reckon will save small businesses plenty of money by allowing them to make free phone calls over the Internet.

They told icWales that their version of the new technology would be a hit - because it's easy to use.

Dan said:

"In contrast to difficult to use and expensive traditional systems, we have made the Teleserver easy to use yet powerful by building on the popular open source Asterix software platform."
