Sergey, if you have questions regarding KAZOO-4326 then you can send to proper mailing list or use JIRA. if you have any other questions concerning kazoo usage (share realm between accounts) then you can also send to proper list. i believe this is not the place for posting and responding to kazoo specific questions. i only pop in here because you stated that it doesn't scale and i completely disagree with that, and didn't want the rest of freeswitch mailing list users to think this statement is true.
