Indeed, and you could even get creative.
For example: Imagine hooking up a vintage telephone booth to an ATA adapter.
"This is a unique large, mid century American telephone booth with a wood
body, glass sliding door, and a vent on top. When the door is closed, a light
automatically turns on and there is a seat in front of the phone."
Sit down, place your call using voip.
And then of course imagine the reverse: The phone booth starts ringing when
someone calls! ("Excuse me while I step into this phone booth to answer the
call...")
Very retro but with modern coolness!
