Tony Romo calls plays. He doesn't call Carrie Underwood.

Sources close to the Cowboys QB tell TMZ Tony "is not calling Carrie" -- despite a recent interview she gave implying that she's ducking Romo's calls.

In fact, Tony's been spending all sorts of "quality time" with on-again-off-again-back-on-again girlfriend Jessica Simpson -- we even got the proof when they left dinner together in Malibu over the weekend.
