All of those, both ARPU, average revenue per customer is up, I think, quite materially. X Series, we feel for the larger customers, this mix and match is extremely critical. And I think you're seeing it just in the strength of the customers we're winning and we're winning them globally. You are often finding customers will buy just the contact center and then evolve to telephony or they may buy just our business communication system and then evolve to the contact center, and then over time, they have plan to add in video collaboration. So from that perspective, this gives them essentially a future proof system. So we have seen our big deals accelerate quite dramatically, and as I said, globally.

And the good news for us has always been that upsell has always been about 50% of our bookings. This quarter, it was a little lower, and that was mainly because new logos were significantly higher. So new logos were about 60% of our new bookings versus about 40% -- and 40% were add on. But the great thing about having new logos is each of them will add on, and so over time, you keep building stronger and stronger book of business. But I cannot overemphasize enough how proud I am of the ability to sell contact center. Our team sold contact center -- I mean I'll give you 3, 4 examples of customers, a large elevator manufacturer that everybody has heard about, a very large government agency in Britain, a very large international university, they bought us for a contact center stand-alone, and then over time, will migrate to our business communication system. That's unique for us. 40% of our bookings for mid-market and enterprise was contact center, either bundled or stand-alone. And so that says, in essence, what was essentially a company that basically sold business communication systems and then combo deals where we added on contact center, now can sell contact center stand-alone and contact center can potentially pull in our business communication system. And right after that, we're ready for video collaboration, so we've built three best-of-breed technologies under one single platform.
