Mobile telephone hosted meeting controls

Technologies are described herein for controlling components associated with a room using a mobile phone. A gateway is configured to receive a command from a mobile phone. Upon receiving the command, the gateway determines whether the command is a room command or a presentation command. If the command is a room command, the gateway causes the room component to respond to the room component. If the command received is a presentation command, the gateway causes the presentation component to respond to the presentation command. A user may input commands to the mobile phone by making gestures with or on a screen of the mobile phone, by utilizing phone keys of the mobile phone, or by interacting with user interface controls displayed on the mobile phone.
