If you are going out of office but still leave something interesting for your contacts like poetry, that’s something really out of the box. This is a truly amazing OOO message, and reverting with poetry will surely make the receiver read it twice as emails are the last place one imagines reading poetries. Especially closing with “If all else fails, clear your cache…” is one good way of telling people that they will need proper help and it will anyway take time before they’re all set. Have a look at it here:
But I also believe there’s meaningful power in the mundane cultural norms we set and practice. Email, for better or worse, makes up a large chunk of how knowledge workers communicate. So much of this communication is muddled by broken email habits and larger anxieties around performing productivity. We’re constantly nervous about asking too much of others or doing too little on behalf of our coworkers. But we’re also stuck in work patterns that force us to communicate constantly and normalize working and demanding things from colleagues at all hours.

Voice mail is a strictly worse medium than almost any alternative. You don’t get the opportunity to converse and ask questions back and forth like you do with a phone call; you can’t extract information efficiently from the message like you can with an email (the old “ugh, I have to listen to this entire message over again just to check one thing he said at the end” scenario).
Even if I do have access to my email while I’m vacation, I typically do “I’m out of office with no access to email or voicemail until (date). For anything requiring immediate attention please contact (boss).” If I happen to check my email I can still forward the important ones, but otherwise hopefully people get the message that I will not be responding.
