VoIPUser.org, an open VoIP community, nominated in "The 50 Most Influential People in VoIP". It is known for its web forum, free VoIP service based on SIP, plus their reviews of VoIP devices, books and services.
It is pretty much impossible to reproduce Dean Elwood's speech, you just have to get the opportunity to listen to him. He is a lawyer day by day and his hobby is the VoIPUser, but I felt the opposite. He co-founded voipuser.org with the aim of building a place for "experimenting new stuff". And they did test and experience lot of stuff out there, they built one of the biggest web forums in this area, with a good knowledge base. Many came to the forum as newby and are able to help to others questions in short time.
Still the main goal is to experience new stuff. Privately, he launched an open invitation to for OSP testing. They have available an OSP server, if someone else is interested can drop a message on the forum or send and email to us at <team (at) kamailio (dot) org>. Several plans are to be shaped to touch new stuff and open ways in VoIP and to involve many people and open source projects in such collaborations.
