From an episode of Frasier: Season 11, Episode 14.
If you really analyze the pictures, you can see many fairly rare phones. I see an early Garnet Red AE80, AE21 stick, several WE multilines in different colors, several 500s, a 5302, a Terryphone, and even some Call Directors!
They definitely raided the old prop bins for this episode! This was in 2004, so I would assume Hollywood was no longer using many of these as props, or at least not as much at this point.
