A system is configured to receive a request from a client device to provide web content for a frame in a web document provided by a web server and transmit the requested web content to the client device. The requested web content comprises an application for providing a live chat function. The system is further configured to exchange a first plurality of messages between the client device and another system via the application, exchange a second plurality of messages between a further client device and the other system via a further communication channel, and display a uniform view of the messages on the client device via the application upon determining that the identifiers associated with the messages correspond to a single user. The messages in the uniform view are ordered in chronological order based on the dates and times of receipt or transmission of the messages.
