I understand that. But MS shouldn’t have to solve “route E911 on an Android phone”. Google has to solve that for the default dialer/call handler. I don’t understand why a call made from default Android would ever route back to MS Teams. All calling (at least for E911 and similar) should go through the default call handler via API. Or something like that. It sounds like Google has a really convoluted, error-prone implementation. I’m sure they had a good reason at the time, but looking in from the outside today, my first thought is “WTH were they thinking?”
