A fully-managed link into Microsoft Office 365

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.

Use many options for connecting

Hybrid options 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 who are cloud-ready to the Microsoft public cloud. Alternatively, we can provide a managed gateway to connect your on-premises voice environment to the Microsoft Cloud.
