Systems and methods that enhance or route data messages, for example by optimizing transmission of data packets through a computer network between devices is provided. The intermediary device can receive a data message having a characteristic. A session management mechanism can identify, based on the characteristic of the message and a characteristic of a pre-existing session, a tuple. Based on the tuple, the session management mechanism can modify the pre-existing session to generate a modified pre-existing session that includes the data message. A session lobby mechanism can obtain an indication of the modified pre-existing session and can pool the modified pre-existing session with a plurality of additional sessions. Responsive to a selection received by the session assignment mechanism from a live interaction component of a contact center agent computing device, the session assignment mechanism can provide the modified pre-existing session to a contact center agent computing device.
