Is the sentence correct?
Give me a reminder call when you are ready ?.
Context: I scheduled a meeting with someone at 1 pm. But the person is not responding on chat at 1 pm. So I don't want to keep checking messages or the persons' reply. Instead, I want to tell him to give me a missed call so that I will come to know he is available. I am not sure how else to express this or is there a better way to say this.
give me a missed call correct? It feels like the person may ring my mobile for a sec and then disconnect and so I may not be able to hear the ring in case of a short missed call
