Since Jetpack 2.6 (which shipped November of 2013), we don't actually activate our internal contact forms module if you're using any of the other popular contact form plugins already:

...
https://github.com/Automattic/jetpack/blob/3.1/class.jetpack.php#L83

But beyond that, it looks like Contact Form 7 uses the [[contact-form-7]] shortcode -- which we don't touch. Can you detail how we overrode it?
