Congratulations on your recent entrepreneurship! I owned an ISP in the 90s and PAID an answering service to answer calls after office hours. Two of us would carry the dreaded pager (one of the first SMS devices out) and we'd coordinate who would get the call. I'd take the 2AM calls usually - being the owner and all. A strange thing occurred over time.

A few of the ladies at the answering service started doing simple tech support for the customers. Reboot your modem/computer/check your password. Said they were bored and it was interesting and didn't mind. Ended up giving them accounts for free. The call volume was noticeably lower after that. A few hours without doing dialup tech support is like a slice of heaven.

I feel like this is sorta like that. You can answer a few of the more common questions, maybe get your users to fill out details (maybe a standard form that prints to a handout for the guests even) and use those to populate your agents screens when a call comes in. Stuff outside the scope of the info you gathered gets kicked to the user. They don't get a completely free vacation time, but it's better than it was. Don't promise it'll be 100% interruption free. That means you need to change your marketing a bit, but it's still kinda cool what your offering

Best of luck! Pools of knowledge are going to be big.
