Skype might have been sloughed off of eBay into its own entity, but lawsuits, regarding its core Skype to Skype technology, might put them in trouble unless it has a backup plan of new VoIP tech.

TechCrunch is saying that Skype is looking to buy Gizmo5, a SIP-based service that isn't quite as popular as the former, but works pretty well. SIP is an open standard that works with many, many devices‚ÄĒGizmo 5 works with Google Voice even‚ÄĒso this could be a pretty good move even if Skype gets out of legal trouble. Imagine piping your free Google Voice number through Skype to get free calls like you can now with Gizmo5. [TechCrunch]
