# Using call diversion services (ETS 300)

ETS 300 call diversion procedures can be viewed as a remote-control mechanism to manage the diversion services performed in the network. The messages are command/response transactions, where the command can be:

- Activating call diversion

- Deactivating call diversion

- Determining the current state of the call diversion service (enquiring)

- Informing a user that a call diversion has taken place (notification)

The response acknowledges the successful processing of the command, and may contain information requested by the command.
