One or more MMoIP packet streams are transmitted via a connection established between a first and second endpoint of an IP communication network. The one or more MMoIP packet streams include MMoIP payload data and/or control data. Control data directed to a processor is inserted in at least one MMoIP packet stream of the one or more MMoIP packet streams at the first endpoint and/or the second endpoint. The one or more MMoIP packet streams are transmitted via an MMoIP switch of the IP communication network. The MMoIP switch monitors the one or more MMoIP packet streams. The MMoIP switch detects the control data directed to the processor. The MMoIP switch forwards the detected control data to the processor.
