Very original, I like it! Do you also have the option to schedule a call when either person is not available? Or should you offer your customers to either call you via OnAir, or schedule via (e.g.) Calendly?
Thanks! so, you can add an "offline message" that is displayed when your link is offline. In that case, adding a Calendly link to that message might make sense. Or simply "I'm typically online 12pm-4pm for walk-ins" etc.
