PBX routes Skype mobile calls for free

Getting free calls requires users to run the client on a compatible phone, with a compatible 3 SIM, using a version of Skype downloaded from the 3 network. The required VoSKY hardware varies depending on the number of concurrent lines required and the type of PBX in question, but that PBX must be IP compatible.

The current entry-level VoSKY appliance is the Exchange 9040, costing £900, and capable of supporting four concurrent Skype lines. The company plans to replace this in the coming months with a more expensive model supporting more concurrent lines, the VIS8, costing £3,000, a company spokesperson said. However, the new model was totally plug-and-play, unlike the current one which required a PC for setup, the source said.
