I work there, just saw this.<p>Bluebox was an old project to provide a GUI for freeswitch.  Kazoo has been the focus for the past 4 years, bluebox is now a community project if I recall correctly.<p>Kazoo is a multi-tenant hosted pbx and trunking solution. It is an erlang cluster which uses amqp as a messaging bus and erlang apps which provide centralized call control and features across multiple freeswitch (media server) and kamailio servers (sip proxy). A shared cluster wide database is provided by bigcouch.<p>The difference between this and a cluster of asterisks (or broadcloud, kandy etc) is that you as a user or account, are not tied to a single server, any phone on your cluster can utilize the resources of the entire cluster as the erlang apps and AMQP bus provide a glue joining all servers in the cluster into a single &quot;switch&quot;. Most of the &quot;cloud&quot; telephony out there is not distributed, it is mostly a lot of boxes with at best HA fail-over to another box that sits in as a warm standby with a unified provisioning layer to hide this from the users.<p>You can checkout kazoo at github <a href="http:&#x2F;&#x2F;github.com&#x2F;2600hz&#x2F;kazoo" rel="nofollow">http:&#x2F;&#x2F;github.com&#x2F;2600hz&#x2F;kazoo</a><p>There is a kazoo all in one ISO, which lets you run all the services in a cluster via a single server. You can get it at <a href="http:&#x2F;&#x2F;repo.2600hz.com&#x2F;ISOs" rel="nofollow">http:&#x2F;&#x2F;repo.2600hz.com&#x2F;ISOs</a> version 2 has the new GUI monster-UI.<p>Edit: phone does not a good comment make, spelling broken links ...
