I've experienced this strange issue 4-5 times after OTA-12. It seems pretty random and is hard to reproduce.
When I get an incoming call, the screen turns on, the incoming call pop up appears, but there is no sound at all even though the phone is not set silent (and also the speaker volume is not set too low). I can accept this call and keep conversing as usual.
Once I asked the same caller to call me once again after a few minutes, that time the phone rang as expected.

Device: E5, OTA-12, stable channel

I can provide necessary logs if this happens again.
