Q: Why can't I cancel a current call and pick up an incoming call any more on my iPhone in the car via the bluetooth connection to the car's sound system?

Since upgrading to the lists version of iOS last week, my iPhone functionality via bluetooth in the car has decreased. If I am on a call and another person calls me, my iPhone screen gives me the normal options, one of which is to hang up the current call and pick up the incoming call.  This used to work like a charm.

But since the recent upgrade to iOS 9.2.1, when I'm in the situation described above and I select "hang up the current call and pick up the incoming call", I lose the current call but simply hear the continued ring of the incoming call with no way to "answer" that call and bring it in.

Sounds like a bug in the software.

Any have an idea how to work around this?

I usually can't easily make my iPhone hang up from the ring of the second incoming call in order to call that party back.  It's likeI'm frozen listening to that ring in Phone mode.
