Microsoft Teams Calling

Microsoft Teams Calling

Microsoft Teams Calling, also known as Direct Routing is a cost-effective alternative to Microsoft Calling plans on your Microsoft phone system. Microsoft phone system users can make and receive landline or mobile calls by adding the Hello Teams Calling service. The Hello Teams Calling service is a simple addon subscription that combines the benefits of VoIP with the collaboration capabilities of Teams. 

What is Teams Calling?

Currently, anyone using Teams can communicate with other Teams users without a phone number. Adding the Hello Teams Calling service converts a Teams account into a telephone. This allows users to make and receive telephone calls using their Teams application.

Why should I pick Hello’s Teams Calling service? 

Hello’s Teams Calling is cheaper than Microsoft calling plans. 

Hello’s calling plans easily integrate with Contrex. Users combine all the benefits of Contrex with MS Teams. 

What software is needed before I can add Teams Calling?  

You need to have a Microsoft 365 licence that includes the Microsoft Phone System.

Can Teams Calling replace my existing phone service? 

This depends on your organisation. Teams Calling is suited to staff who already regularly use Teams to make and receive calls internally.

Teams Calling is generally more expensive than a standard phone system due to limited hardware options. It isn’t usually suitable for contact centers or non-office-based environments like schools, factories, warehouses or shops.
