Android 13 adds BLE Audio (Bluetooth 5.3) with the LC3 codec and supports bi-directional audio up to 32 kHz, stereo microphone and hearing-aid improvements. The recommended path for VoIP is the Telecom API rather than AudioManager: it handles device states and routing and exposes methods like setAudioRoute and requestBluetoothAudio, and you can check hardware with isLeAudioSupported. LE Audio offers Recording vs Communication modes; devices hit the market within the next year.
