Here's an example of what happens to me:
Doctor: Call Surgeon and see what his availability is for [procedure]
Me: Surgeon, what blocks do you have open for [procedure]
Surgeon: who is it for?
Me: unknown, I am just calling to see if the scheduling will even work out
Surgeon: *requests more details that are irrelevant as far as the timing of the procedure*
Me: I literally don't have any details outside of what Doctor needs done and needing to know what your schedule is.
Surgeon: Can you call Doctor and ask *list of irrelevant doctor questions* and call me back?
Me: *snappy* SURGEON'S FIRST NAME. Maybe you need to call Doctor yourself because last time I did this, I asked the questions for you, called you back, and then you had more doctor questions that I am unqualified to answer. It'll be faster if you call him directly.
Surgeon: *laughs uncomfortably* umm ok yeah I'll get to him as soon as I can....
Side note: Surgeon and I get along well. We have a working relationship that allows me to be extra direct when he needs it.
