If you’ve gotten used to making call via Google Voice in Gmail but craved additional features, today is your lucky day. Gmail calling now supports multiple calls, call waiting, and hold.
Now when you’re talking to someone you can put them on hold, accept an incoming call, and switch between the two calls just as you can with a real phone line that has call waiting enabled. Even if you don’t intend to pick up a second line you can still place a current caller on hold to effectively mute the conversation temporarily. Hit up the link below to read more about the new features at the official Gmail blog.
