Option 3:

Avaya IP Office Cloud (Avaya OneCloud UCaaS)

There are oodles of hosted solutions on the market at varying prices and quality so what’s different with Avaya One Cloud UCaaS?

  1. Avaya OneCloud UCaaS uses leading-edge container technologies to give cost and deployment advantages over other cloud offers.
  2. It’s not a ‘one size’ fits all solution. You start with a core subscription which includes Telephony, Voicemail and Auto Attendant with AI features and add on additional features, only if you need them for applications like Call Recording and historic or real time Call Reporting.
  3. The feature rich J Series Avaya phones really set this solution apart from the others.
  4. You are not financially penalised for using your own existing IP Phones.
  5. If you don’t want physical phones on desks, the Avaya UC application for smart phones and PCs is amazing.


With Avaya UC, you can:

  • Take communications and collaboration with you across apps, browsers and devices.
  • See your day at a glance.
  • Simplify audio and video conferencing.
  • Create a competitive advantage with contextual communication and collaboration capabilities.
