I have been out the office working from home for more than a year now. After a few weeks of remotely checking VM (and sometimes forgetting for days) I simply changed my phone setting so you cannot leave a message. I have not regretted since. On very few occasions people have clicked 0 and gone to reception. Reception can IM me and ill call or email the person back if I want or they can give them my email. Everyone else either emails me or if they already have it call my cell. Internal people never call my phone they use IM or video chat. No one internally has had an issue with this and this eliminates the whole hey call me back to spend 30 minutes talking about something that I could have answered in 2 minutes in an email.
As an employer one of our policies is to Call in absent days not text them in. This hasn’t worked well as employees ( especially young employees) will still text in those types of messages. It would be wonderful to have a feature in the iPhone that allows for instant text response that can be set up for certain contacts( employees). Something similar to an out of office message in email…” I am not receiving text, please call … … …. and speak to me directly”

My voicemail is set up to forward to my email. I did this years ago, way before the Late Unpleasantness. And it’s perfect for working remotely. (I have trained my students to use email. My colleagues hate voicemail too, so we use email and gchat. Or walk down the hall when we’re live and in person)
My new job provided a template OOO as part of the onboarding brand templates package! I’m sure it might seem like overkill to some, but I’ve had tons of nervous first-job employees ask me what theirs should say, so I loved that they just gave a sample to go from. Also goes a long way in communicating that unique office culture stuff that is usually unspoken/not formalized.
