While they are not actual phone calls (even though I could), I use Streamyard to go live to many different platforms (Facebook, Youtube, Twitch, and more) and I plug my microphone into my Rodecaster Pro II. I am on challenge one. My co-host is on channel two. We are both connected to Streamyard so we can hear each other.
My phone is connected to the Rodecaster via bluetooth. The Rodecaster is around $799. You can also do this via the Zoom Podtrak P4 (around $200) and you can connect your phone to the Podtrak P4 via a TRRS cable.
