You’ll really like this then, it’s a clip of Phil Hendrie who I recently discovered. He does tons of voices and sound effects, his studio has multiple microphone and switches between them for different speakers.

Here is a clip of him when someone called his studio thinking they were the local Pizza Hut. Phil does all the other voices, including the phone system.
