Is "live in China" good enough? How big is the variance between
different regions, providers(?) etc?

Which of the two?

busydetect will work almost always. But it is suboptimal: it may sotimes
accidentally detect running calls. And it takes a few seconds to detect
a hangup.

If the provider sends you polarity events, you should be able to see
them as debug messages of Asterisk (if debugging is turned on).
