I have to disagree to some extent. The call quality on the StarTAC was horrid - it sounded like it was sampled at around 2kHz most of the time. (And to be fair all other cell phones sounded the same at the time.)
When calling on my iPhone the call quality is significantly higher in many cases. I'm not sure if it requires both callers to be on an iPhone or on the same carrier or what. But sometimes the calls are as good as the audio coming from the Music app. Other times, they sound like StarTAC calls. But something has definitely changed in the last few years for certain types of calls. (And I've found FaceTime audio calls are always high quality audio.)

And the GSM bitrate and codec was chosen to pack as many voice calls as possible into the bandwidth of the GSM protocol. That said, if it is iPhone to iPhone, it may well be that the call never touch the carrier systems and instead happens over iMessage for all i know.

- digi_owl 10y agoDo you have to opt in on every call, or will it happen automatically as with messages?
