Yes, you can use Receive Task. To know that task is staretd use execution listener.

<receiveTask id="waitTask" name="Wait Task">
    <extensionElements>
        <activiti:executionListener event="start" class="SendMessageExecutionListener"></activiti:executionListener>
      </extensionElements>
</receiveTask>

Listener must implement ExecutionListener interface

public class SendMessageExecutionListener implements ExecutionListener {

    @Override
    public void notify(DelegateExecution execution) throws Exception {
        //send message here
    }
}

And when subsriber handles message signal process to continue.
See more details in Activiti User Guide Java Receive Task section.
