Anyone with Windows Insider access has had access to the call feature since October 2019, but it's officially available for everyone today. However, the only phones that are compatible with the Your Phone app's call ability are Android phones. Sorry, iPhone users.
With this functionality, you don't have to move your hands away from your keyboard and mouse to respond to a text message or to answer the phone when you're gaming or working.
All you have to do is download the Your Phone app on your computer and your Android smartphone, link your Microsoft accounts and pair via Bluetooth.
At least that's how it's supposed to work. My phone connected seamlessly to the texting and image portion, but the Calls tab gave me this error: "You have apps installed that prevent you from making calls." I restarted my PC and went through the troubleshooting process that it linked me to — no dice.
When the Your Phone app does work, it will display your contacts and also present a dial pad. Clearly Microsoft isn't done sorting out the issues, but it might work for you so we suggest giving it a try anyway.
