I posted something similar here:

In my case, the phone number is redirected; I think Apple's bot gets confused by the two levels of ring tone and hangs up too soon.
You could file a bug, ha ha. Mine was closed with "too little information to diagnose".
Is there anything else that I can do here?
The easiest solution is probably to buy a "burner phone", use it once for this verification, and then dispose of it. I'm going to wait before doing that, in case they fix it.
It may also be that they remove the requirement to disclose a phone number. I think that's less likely to apply in your case if you do literally have a head office with a receptionist, but for all the one-guy-in-his-garage businesses that literally don't have a business phone number, Apple's interpretation of the rules could change.
Please let us know what happens in your case.
