# Remind diversion service (ETS 300)

If the served user activates call diversion services, whenever the served user initiates an outbound call, the remind diversion services can remind the application that call diversion services are active. If the remind diversion service is active, an acu_ss_reminder_diversion_invoke supplementary service structure is returned to the application in the first incoming call control message.

Any incoming call control message, such as ACU_CONN_CO and ACU_ALERT_IN, can carry the remind diversion message.

Remind diversion can optionally be activated when the user first subscribes to PRI services. It cannot be remotely activated or invoked by the application.

If the application activated call diversion only for calls of a specific basic service type, the remind diversion message is returned only when the served user makes an outbound call of that service type. For example, if the application activated call diversion only for teletex calls, the remind diversion message is returned only when the served user makes a teletex call.
