I like that you can use it both as an app or website so if your internet goes down then still have access for calls! Have not used this at all but did some research before purchasing about what they could offer me in terms of features/benefits etc... There are very few things i dislike other than having no option when using via mobile browser (app store) - would be nice there was one more way available rather just through google play? Overall cost effective solution with excellent customer support from time2time experts who know how businesses work!! So much better value compared even our traditional landline phones which were costly per month. Great product great prices easy set up call quality never fails best thing we've found yet- Highly recommended highly recommend taking advantage of trial period too get everything working out perfect first go around otherwise will waste precious money later!!
