Method and system for providing a user with a consistent view of user session requiring a conversation between an external device and application servers in a distributed computing environment. The conversation may be established by receiving a call at a routing device from one of the application servers or the external device to reach the other to establish communication therebetween, opening a session for the conversation, creating a session ID that uniquely identifies the session, adding the session ID to the call, storing the session ID, and routing the call to the other of the application server or the external device. If the call already includes a session ID, then the conversation may be established by routing the call to the other-of the application server or the external device, and allowing the conversation to join an already opened session that is uniquely identified by the session ID.
