CoCon messaging and services is a software license within the CoCon conference control software suite that activates additional functionality on the uniCOS multimedia conference system. The messaging functionality makes it possible for delegates to type short text messages via an on-screen keyboard and send them to other delegates or groups of delegates. For privacy reasons sent messages are not stored in the system and cannot be consulted through the system afterwards. The services tab on the uniCOS delegate unit allows the user to request any service as defined via the CoCon software. Without having to leave their seats and disturb the meeting, delegates can ask for coffee, a pen, paper or any other kind of service that has been set up in the software.
