Well, look I think on the Cloud Fax side, the real driver is our approach to these verticals and healthcare being at the top end of that. We are solving a real problem in that industry, you can't go a week without people, sort of complaining about the paper-based approach of healthcare, we bring that digital interoperability that they are looking for, but our market share still is small, healthcare takes a while to adjust. But we're now trying to force that issue through product development through sales, through marketing and being not waiting for the phone to ring, for hospital system for instance to switch to our Cloud Fax solution. But for us to get in there and convince some of that and to handle them do that, right. So, I think that's what you're seeing there. And I think we're uniquely positioned in that marketplace. I don't think there's quite anyone like us that that can do this in healthcare. I think on the voice side, the part of the business that is most of the businesses the second line business that I referred to, which I actually think from a market point of view is people talk about the gig economy and you talk about more and more people being independent and freelance in orientation, they often view their laptop and their phone, they don't want to carry two phones, and they don't necessarily need a second set of hardware to be able to provide a professional face to their business. And so, we like it, we think it's a good space to be in, we think the markets growing, we think we're one of the larger providers, there are some smaller providers in this space, we think that they would be natural role of candidates, because we do think now between eVoice and Line 2, we've got the best of breed in second line. And so, we like the space and it's one where, we think there is some good cross selling opportunities, that is something that we are now exploring in earnest within cloud, which is trying to push these services. Now something that's been talked about, I think a lot been done and the general managers are forcing that agenda too. So, I think the both spaces where we're not running into real competition.
