It's not the same, but I'm using Zello (IP walkie-talkie basically) with my wife and it is very convenient. For example when we are in a shop or have to quickly sync on something, especially if you have children. I imagine it could be quite helpful for remote work, but it depends on many factors, work time is one of them.
