The Yay.com team were exceptionally supportive in getting our team's VOIP service transferred from our previous supplier and also in helping us set up new users and hardware as and when needed. The VOIP service itself is miles ahead of our previous supplier in terms of quality and reliability and the intuitiveness of the online user interface makes it easy for us to manage changes and get the most out of the services functionality on a day to day basis. It's also well worth checking out the new mobile app which is incredibly easy to set up and use and again far better than alternatives third party solutions we have tried.
