Shouldn’t it be about choice and personal preference and style

While it may be quicker to read an email than listen to a voicemail, isn’t it quicker to leave a voicemail than type an email?

Use what works for you and accept what works for your colleague.

People just need to use what is available to them in a productive manner. I see pros and cons to both voice and text methods. Personally I prefer text methods but it would be naive to say that voicemail is dead.

I have never done this. I don’t act like a tech snob and exclude people who choose to communicate with me via voicemail just because it doesn’t meet my standards. I’m all about using tools though to make better use of voicemail.
