αναπάντητος

When I see a missed call, I call back immediately.

As soon as I see your missed call, I will call you back.

Having finished the video conference, I looked at my mom’s missed call and called her back right away.

The missed call from my coworker worried me, because tomorrow we are loading the boxes for the company outing.

Having seen the missed call, I understood that something urgent had happened and left immediately.
