Sure. So just to unpack the numbers, and then Alan can comment on this as well. If you look just -- if you go to table 2 in the press release, and you look at service revenue versus product revenue, you will actually -- in business, and you take out Nexmo which is the revenue of which is footnoted, you will actually see this product revenue that went down in the quarter. If you look at service revenue, it's actually up $2.6 million just in UCaaS in the quarter to that $2.6 million of organic growth you add service credits, which were $300,000 to $400,000 elevated in the fourth quarter, so you then got a quarter that has $3 million of service growth and did not benefit from some one-timers that we had in 3Q, which included a USF increase which is not in service, but it's in total and some other equalization of fees. So when you put that altogether, we actually had a strong organic growth quarter in UCaaS. The other component that is working against, that you’re seeing in product is bad debt on equipment. So we had about $300,000 there, but that cost a $600,000 swing because that $300,000 was -- it was $300,000 higher in 3Q and it should have been and we took that out of 4Q, so that actually made a $600,000 swing there. In addition, on equipment, we are increasingly moving to a rental model, so you’re taking money out of in quarter and you’re spreading it over subsequent quarter. So you can -- really a lot of the difference relative to expectations within product for the reasons that I cited. In terms of long-term growth and growth for the year, really goes back to what we said before, which is we believe this is an achievable plan that reflects a fully built machine at the low-end -- at the lower end of the market where we're absolutely doing everything we can and feel like we have a very, very strong position in that market and then continues to build out and continued execution of the longer sales cycles at the midmarket and particularly in the enterprise.
