What happens when you call the extension for the RAD? do you hear the "random recording?"

What do you hear if you call the voicemail pilot? Is the voicemail auto-attendant message the "Random recording?"

Why is there a RAD in the hunt group? Is that the voicemail hunt group?

This sounds like someone tried to get the function of an ACD without buying ACD licenses, so they forwarded the Auto-attendant to a hunt group with a RAD in it.

OR, the "Random Recording" is the auto-attendant, and when a room is not checked in, the call gets diverted there because the voicemail can't send it to a mailbox. then it transfers to an operator.
