Michael Robertson, founder of Gizmo5, which recently released a service that enables free calls to Skype called OpenSky, calls the new Skype-for SIP service vaporware.
It’s great to see Skype inching towards a more interoperable world with their Skype for SIP service. Even if this is complete vaporware at least their heart is in the right direction. Last year they announced Skype for Asterisk which is still not yet released and it’s unclear what the pricing will be. Skype For SIP is similar in that it is not yet available and pricing details are murky but both are steps in the right direction.
Hard to dismiss Michael’s argument, though one has to point out that Skype for SIP does impact his business. Fellow VoIP Blogger Tom Keating heard from a Skype spokesperson:
“The product is available now. It’s using the same Skype technology that has been tested & deployed for the last 5 years. He’s saying December 2009 – that’s not the case.”
