Yes, we have 5 phone numbers for different purposes and they all ring the same 2 agents (small company). There are actually 2 queues for each phone number because it rings the first queue for 15 seconds and just plays the standard "ring progress tone", as normally the agent will pick up on the first or second ring, and just moves to the second queue after the 15 seconds where it plays music on hold if they can't answer in time. It is nice to be able to play a different ringtone for each phone number (so 5 in our case) as that helps them know what the customer is calling about without having to look at the phone. So since we have 2 queues for each phone number it would be nice to have 10 different Custom Queue Ringtones in our case.
