Extending Enterprise Voice to Microsoft Teams

End-to-end management of Microsoft Teams, UC and collaboration solutions, and enterprise voice, enabling you to take control of your UC estate.

Enterprise Voice - Extending the Reach of Microsoft Teams

Microsoft Teams is a success. Delivered as part of the Microsoft 365 suite of applications, the power of Microsoft Teams is now harnessed by over 90 million subscribers globally, who use it daily to collaborate and work together.

As a result, Microsoft Teams has firmly established itself as part of the IT communication ecosystem. 

Businesses are taking the next step: To assure their UC platform with appropriate management tools, and to extend Microsoft Teams into enterprise voice. As such, users have a service they can depend on, and they can use the same client and application for all of their collaboration needs.

VOSS provides end-to-end management of Microsoft Teams, UC and collaboration solutions, and enterprise voice, enabling organizations to take control of their UC estate. Businesses depend on Microsoft Teams and Microsoft Teams runs better with VOSS.

Alternative Solutions from Cisco and Microsoft

For enterprise voice, Microsoft provides Calling Plans (now known as Business Voice). These come in two flavors for domestic or international calling, can be added to a user’s license, and provide an easy and simple path to introduce telephony. They are most suited to smaller organizations with less complex needs, and do not meet the demands placed by larger organisations for their enterprise voice service.

Many larger businesses run their enterprise voice service on Cisco. Cisco in turn provides a Jabber add-on for Microsoft Teams, allowing users to make and receive telephony calls. The add-on is installed on the desktop, requires a Cisco license, and only operates when connected to the corporate network. It does make use of its own (Cisco) dial pad and with this in mind, is best suited to enterprises that want to keep enterprise voice and Microsoft Teams at a distance.

Microsoft Direct Routing – Teams and Telephony

The majority of enterprises connect telephony into Microsoft Teams through a Microsoft supported technology called Direct Routing. This offers a 'break-out' point for users into enterprise voice – for making and receiving telephony calls. It also offers enterprises a better level of call control, allows the use of existing numbers and commercial contracts, and is installed without major disruption.

In its basic configuration, it operates as an island and does not offer easy integration with existing applications (such as call recording or contact centres), or enable migration of users to Microsoft Teams, or leverage the investment already made around existing enterprise voice platforms.

The Best of All Worlds - Adopting a Hybrid Approach

The answer lies in adopting a hybrid approach. In this deployment, Microsoft Direct Routing is used to integrate the Microsoft Teams service into the existing enterprise voice platform, providing a single, unified solution. This approach builds on the benefits of Microsoft Direct Routing and adds: 

  • Users may freely communicate between any end-point, using either internal extension dialing, E164 or through a user’s contact card. Calls are kept on-net as required, to avoid unnecessary call charges.

  • Existing hand-sets may be retained alongside users with Microsoft Teams, allowing access to a wide range of devices to suit individual requirements. User profiles are available for Cisco (only), Microsoft (only), or multi-vendor (both Cisco and Microsoft devices and clients).

  • Dial plan controls and PSTN break-out points can be reused to provide consistent dialing (including emergency calls) and robustness on the solution.

  • Migration workflows can move users, as required, from the existing voice platform and onto Microsoft Teams without any major disruption.

  • Existing applications, such as Call Recording and Contact Center, may be extended out to users on Microsoft Teams.
