Do I need to purchase pre-requisite Microsoft licences from Telstra?

If you currently purchase your licences from another Microsoft Cloud Solution Provider (CSP), then you will need to move your pre-requisite licence subscriptions to Telstra in order to purchase Telstra Calling for Office 365.

Customers under a Microsoft Enterprise Agreement (EA) can continue with their pre-requisite licences provided from Microsoft directly, and purchase Telstra Calling for Office 365 separately from Telstra.

Does Telstra have to be my Microsoft Cloud Solution Provider (CSP)?

Yes, you must authorise Telstra as your delegate CSP in order to purchase Telstra Calling for Office 365. This is even the case when your pre-requisite licence subscriptions are with Microsoft Enterprise Agreement (EA).

Why does Telstra have to be my Microsoft Cloud Solution Provider (CSP)?

Telstra must be a CSP for your Office 365 service in order to provide assurance and support for this voice calling service. Telstra must therefore remain an ongoing administrator of your tenancy for the duration you are using TCO365. Telstra would not be in a position to comply with assurance service levels and therefore reserves the right to cancel your Telstra Calling for Office 365 as it becomes an unsupported service configuration.

In addition to this, all current and future pre-requisite licences must be linked to the TCO365 licences in the Microsoft Administrator portal in order for Telstra to provide support of the service.

How do I purchase?

Telstra Calling for Office 365 is provided on a monthly plan per user attached to compatible Office 365 licences (purchased separately). You must choose one of the below calling plan types across all users. The service is purchased and billed monthly via the Telstra Apps Marketplace.

Wireless Communications will assist you to evaluate your current call spend and recommend the most appropriate calling plan for your business. We can then assist with the application and ordering process to ensure that the experience is seamless and your business continuity is maintained throughout the transition to TCO365.
