People are weird and sometimes things don't make sense from their existing framing. What if the URL was OnAir.com/555-555-5555 <~ basically make it look like a phone number and make it something where people can see they can text, call, or message. If you're live, it shows that. If you're not live, it gives you a way to leave a message. The interaction is almost exactly the same, but might create less friction of "what is this" by making it feel like how phones and contact points have worked for years.

I strongly feel this should NOT be allowed, at least unless you can prove ownership of that number in the real world. Else you'll have scammers registering the number of every bank and airline in no time flat.
