Starting with March 1, 2010 we changed the licensing methodology on VoipNow Platform. VoipNow Core is now more affordable for small customers with the new, dedicated server license for up to 250 concurrent calls. While this is a single server license, it expands to a 4Grid infrastructure able to sustain as many calls as you like. The pay as you grow, infrastructure wide licensing method is still available. In a service provider environment VoipNow Professional is available on pay as you grow licensing and also on dedicated server licensing for a small number of extensions. Perpetual (owned) licenses are available only for business customers.
