  • Appropriate for as few as 8 users and powerful enough for 2,500 spread across multiple locations.
  • Our unified call control delivers voice, video, instant messaging, visual voice mail, fax, phone twinning and specialized call handling rules across multiple devices and platforms.
  • From Windows to MAC and from IOS to Android, all services are delivered in a consistent, reliable manner.
