How does Telstra Calling for Office 365 work?

A complete, cloud-based solution for modern collaboration


It's all made easy

Telstra Calling for Office 365 removes the complexity of managing a dedicated PSTN network. We provide a fully managed link directly into Office 365, so all you need is adequate internet access. There's no need for complex technology roll outs.


Each user is allocated a phone number associated with their Office 365 client. You can choose to migrate or port your existing landline numbers, or allocate new ones via the administration portal.


Choose hybrid for more flexibility

Hybrid is ideal if you're not ready to move voice completely to the cloud. Host complex users in the Telstra private cloud, and move those ready to the Microsoft public cloud. Or we can provide a managed gateway to connect your on-premises voice environment to the Microsoft Cloud.


We'll be with you all the way

We'll help you at every stage of your move to the cloud, from consulting and design, to deployment, management and 24/7 support. Our network of specialist channel partners can also assist you in more places across Australia.
