Isn't this kind of already the case? I thought past 4G there were no separate channels for call audio, it was effectively just VoIP
- emeril 4y agopretty sure that call audio gets much better prioritization for low latency (though at relatively low bandwidth) than higher bandwidth non-voice data?
- simfree 4y agoThe QCI (QoS Class Identifier) for carrier provided voice and video (Android only) calls is generally much higher than normal data, and carriers monitor call handoff reliability between towers, Mean Opinion Scores (MOS, a rating of the audio experience of each call), and device specific performance.
