cisco 7911 phone service implementation

im using a cisco 7911 phone and need to implement a service that will turn on/off the room light .. the thing is after i have selected the service (turn the light on), the phone tells the server to activate the script i installed on the server but what is the device that i can use and that can communicate with the server and turns the lights on or off ?

You could use an E&M card that can present or remove 48v to drive a relay.
