Why Microsoft Teams Direct Routing is the must-have solution for your business

Microsoft Teams has become a staple of the business world. Part of its boost in popularity has been thanks to working from home becoming the norm in recent times. The fact it is currently one of the fastest growing products in the world should come as no surprise. Microsoft Teams handles internal communications, meetings and offers options for document management and app integrations. But did you know you can also use it as a platform to make business calls?

By now, pretty much everybody has made calls using Microsoft Teams, including in a business context. Many organisations are even choosing to use Microsoft Teams for business calls to improve the customer experience and simplify their IT infrastructure even further.

Outbound and inbound calls to other users of Microsoft Teams are free and immediately applicable, but if you want your employees to be able to call "normal" phone numbers (on the PSTN network) as well, then there's some extra steps.

Do you want to use Microsoft Teams for business calls? Then you'll need to connect the Microsoft Phone System (a virtual PBX hosted by Microsoft in the cloud) to the public telephony network. You can do that in two different ways: You can use Microsoft's Calling Plans or set up Direct Routing through a service provider.

Let's have a look at the differences between Microsoft's Calling Plans and Microsoft Teams Direct Routing, so you can make an informed choice.

What Are the Microsoft Calling Plans?

The Calling Plans of Microsoft are the business telephony solution that Microsoft offers directly to users. It includes a phone number for incoming calls and a bundle of call minutes for outgoing calls. A company can choose a domestic or international subscription, depending on its needs. With this solution, Microsoft Teams supports the ability to make VoIP calls to other Teams users, from and to landlines and cell phones on the public telephony network.

Advantages and Disadvantages of Microsoft's Calling Plans

With a Microsoft's Calling Plan subscription, you can get started right away without an external intermediary provider. Does your organisation have fairly simple telephony and phone system requirements? If so, this could be a good solution. However, there are limitations; although the subscription bundle is fairly generous, the monthly license fees are quite high.

In addition, Microsoft's Calling Plans are only available in a few countries (16) through specific carriers. This makes an international rollout more difficult. The Calling Plans are a self-service solution. Support is limited, which can be difficult for organisations with more complex telephony requirements. Also, it is difficult to port existing phone numbers.

Microsoft's Calling Plans are a great choice for smaller companies, who have few requirements for a business calling solution or who only operate in one country.

What Is Microsoft Teams Direct Routing?

Microsoft Teams Direct Routing connects the Microsoft telephone system with the public telephone network. This is done in collaboration with a (SIP Trunk) service provider in order to provide a complete and flexible solution. The SIP Trunk platform is connected via a certified Sessions Border Control (SBC) to the Microsoft Phone System telephony platform. The Direct Routing Module gives companies the flexibility to configure their telephone connectivity as they wish.

Advantages and Disadvantages of Microsoft Teams Direct Routing

Microsoft Teams Direct Routing is a customised solution. This makes it often cheaper and more flexible than a Calling Plan. With Direct Routing you don't pay for a bundle of minutes upfront, but you make use of advantageous per-minute rates, which can even be tailored to your needs for high volumes. This way you don't pay for minutes you don't use and the monthly license fee is significantly lower.

Direct Routing is also a fully managed service, in addition to providing the basic PSTN connection. The provider takes care of porting existing numbers and the reachability of the phone numbers inbound and outbound.

Does your company need flexibility, support and global coverage? Then Microsoft Teams Direct Routing is a suitable and even economical choice for you!
