A phone either rings or it doesn't. It can't start to ring. When we "start to" do something we begin to do it but we don't actually do it. On the other hand, when we "start doing" something we are actually doing it. We may continue doing it or we may be interrupted, but we are actually doing it.

"I figure I'd better answer it" means the person decides to answer the phone. The phrase "it turns out that it's my mother" means that he realizes that it's his mother on the phone.
