Direct Routing is a way to provide a PSTN (Public Switched Telephone Network) connection to Microsoft Teams users so that they can make and receive external phone calls on any device using Teams.
Traditionally, internal, and external business telephone calls have been delivered using a Private Branch Exchange (PBX) phone system, usually located on the business premises. Microsoft Teams can now be used as a business telephony solution, replacing an existing PBX phone system and its associated equipment and costs with a cloud-based system, to provide full PBX voice calling capabilities inside and outside your organization. To enable direct routing, you will need the following:
A Microsoft Phone System (formerly known as Cloud PBX). This provides call control and PBX capability in the cloud with Microsoft Teams.
Connection to and from the Microsoft Phone System to the Public Switched Telephone Network (PSTN). There are two ways to achieve this:
Direct Routing – connects the Microsoft Phone System to the PSTN to deliver calls via an existing or new third party telephony provider, with their associated tariffing and pricing. These appeal to larger enterprises with multiple locations.
Microsoft Calling Plans – Internal and external calls are delivered with Microsoft as your PSTN carrier using Microsoft’s price plans for domestic and international calls. These tend to be more popular with smaller organizations.
