can I send and receive phone calls by voice using 'BlueAnt S4 with Pixel 2'?

[Android Central Question]

I'm a quadriplegic and need totally hands-free technology. Unfortunately, the Pixel 2 doesn't let me answer incoming calls by voice. I can send and receive texts and send phone calls by voice, but can't answer. I've had a BlueAnt S4 for about 8 years paired with a Samsung flip phone where I can send and receive phone calls but not texts. Will the BlueAnt S4 work with the Pixel 2 allow it to do all 4 operations?
