Yes, this is the (rare) use case for the first call you make to a stranger. If you have a pre-existing relationship with a particular lawyer or doctor, you tap on their name or face in the contacts app.
Like, thinking about this I understood that don't know the phone number of my wife. I (probably?) have it written down somewhere outside my phone, I had known it by heart many years ago, but life was different back then, and as far as I recall it may be that I have not used it in any meaningful way for more than full ten years.
I recall that I have given her phone number to others on some occasions, but it involved sending a contact - possibly the number was displayed at the screen during that process, but neither I nor the receiver really read it, and it that way even before smartphones were a thing and sharing a contact happened over SMS.
