Will call answer/end and volume controls work inside Teams?

On well-supported devices, yes, and it makes a real difference in busy schedules. Being able to answer and end calls from the headset helps when you’re away from the keyboard, and on-headset volume control is useful when a meeting runs louder than expected. If you’re buying for a workplace, check whether the model supports these functions across your operating systems and whether firmware updates are available. Many MS Teams certified headsets also include call indicators that help users manage meetings without constantly checking the screen.
