About OnAvaya

OnAvaya is a cloud communications system from Avaya for midsized businesses. It handles voice calls in both directions and bundles unified communications tools into the same service, so staff do not need separate products for each channel. The vendor describes it as a cloud system rather than a box installed on site.

What OnAvaya offers

  • Inbound calling — takes incoming customer calls.
  • Outbound calling — supports calls made by staff to customers.
  • IVR — interactive voice response menus that route callers.
  • Unified communications — built-in collaboration and messaging capabilities.

Who it works with

The system is positioned at midsized businesses that want telephony in the cloud rather than on-site equipment.
