title: How to communicate different integration services in IIB?
body: <p>I using IIB to make a ESB project with 2 integration services.
  One for register account, and one for access database.
  I can do with SOAPRequest node for Request and recieve Response.
  But now i'm trying to using another way to communicate 2 services.
  I know IIB have Label node, but it just work internal service, not for 2 different services.
  So how can I communicate 2 service in IIB without SOAPRequest ( maybe Route node or something). Its like messages can go one by one service.
  Tks !</p>
