Turns out that's because I'm setting sound IO explicitly, even to the default, built-in, devices. And if, when on the call, I'm switching to the headset from my app, it exits with the same assertion.

Nothing happens and pjsua retries to open the device again and again. Then standard dialog box from the OS appears that says that bluetooth audio failed and there is a button "Stop using headset". After pressing the button pjsua prints out the last two lines, and returns to its default state with no active calls. During all this, default sound IO in the OS are Internal Speakers and Internal Microphone.
