Peerio444 is a new peer to peer VoIP application. Their FAQ makes a lot of claims, but is short on details. I’ll have to download it to see what it will really do. They claim it supports SIP, but we’ll have to see if it can actually dial a SIP uri. They call it serverless peer-to-peer telephony.
A: No, unlike similar VoIP applications, users are not restricted to calling other Peerio444 users. They may call a user of any standard VoIP application and any number – including mobile phones, 800 and international numbers – with Peerio444.

UPDATE: You cannot actually download this application. The site says it’s available, but there is no link to download it.
