6Testimonials

  • "When Microsoft announced that they were becoming a voice over IP solutions provider we felt that that was a natural choice. We went through three pilots hosting Skype for Business VoIP with Microsoft being the cloud host provider. The pilots went great and quality of sound seemed to be mostly good. We found that we really needed a solution that included 24/7/365 US-based support."
