I understand I'm not the first to report this, but I haven't seen a solution yet.
Both in my own implementation and in the demo client (vapi.ai/?demo...), if I'm connected to a bluetooth device BEFORE starting the cal, the sound goes out to the device speakers, instead of the headset. Things seem to work fine on Mac. Haven't tested other devices yet.
The funny thing is, if I connect to the bluetooth device DURING the call, the stream is then correctly directed there.
Any idea? 🙏🏻
