Advantages of Microsoft Teams Calling (Direct Routing)


Consolidate your internal and external communications into one hub! Using Microsoft Teams with Direct Routing allows all users across your organisation to utilise a unified single telephony hub with any Teams enabled device whether they’re in the office or on the road.

Cost and Scalability 

On premise telephony hardware is expensive and time consuming to install and maintain. With Microsoft Teams, there is no need to manage on-premise PBX equipment. Easily add, modify or remove Microsoft Teams users as your business grows, and only pay for the resources you need.


Microsoft Teams Direct Routing has a simple and intuitive interface. You can also access traditional PBX call-handling functions such as call hold, transfer, forwarding and voicemail all from the cloud, with little training required for new staff.

How does it work?

Your business may currently be using a Public Branch Exchange (PBX) phone system, which is traditionally how internal and external phone calls are delivered in organisations. Microsoft Teams can now replace your PBX system (and all associated costs and equipment) with a cloud-based alternative, allowing you to bring all your technology, tools and voice solutions in one place.

Direct Routing is a way to provide a public switched telephone network (PSTN) connection to Microsoft Teams users in order to make and receive external phone calls on any device using Teams. Use your existing telecommunications provider to directly connect their SIP trunks to Microsoft Teams.

Case Studies

Get business driven results with eStorm.

The internal IT Manager at Silky Oaks left with no notice and very little documentation. Silky Oaks approached eStorm to assist in keeping their systems operational while they assessed their ongoing IT requirements.


Lighthouse Christian School promoted their junior technician to a management role after the departure of their previous IT manager. The new manager felt he was still developing his IT knowledge and experience, and thus would not be able to single-handedly run the school’s IT. LCS then endeavoured to find a Managed Service Provider that could provide supplemental IT support and services.


To meet the needs of a large client, Liquid Animation worked with eStorm to architect a solution that allowed international animators to seamlessly access data. This was achieved using a combination of cloud-based work stations and Amazon Web Services.
