Microsoft Teams Phone brings intelligent, cloud-based calling to Teams, streamlining operations and delivering secure, reliable voice experiences. Until recently, however, enabling enterprise calling in the contact center meant deploying separate solutions, adding administrative complexity and redundant costs.
Today, we’re excited to announce the general availability of Teams Phone extensibility for a growing ecosystem of contact center solutions, including Microsoft Dynamics 365 Contact Center. This new capability allows customers to extend Teams Phone investments into the contact center, enabling customers to use a single, integrated calling solution across both unified communications (UCaaS) and contact center (CCaaS) environments.
Organizations can leverage Teams Phone extensibility to:
- Apply existing Teams Phone licenses to enable telephony for users of Dynamics 365 Contact Center or other certified ISV contact center solutions1.
- Avoid procuring, configuring, managing, and training users on a separate phone system for contact center deployments.
- Leverage the broad geographic availability of Teams Phone through calling plans available in 36 countries, Operator Connect in 96 countries, and Direct Routing globally.
- Benefit from the extensive features of Teams Phone, including the familiar Teams management interface.
With these benefits, you can now streamline your telephony and reduce the number of solutions to license and manage across your organization. Learn more about the features of Teams Phone extensibility including conversational AI integration.
Unify your calling capabilities for time and cost savings
Teams Phone extensibility is a significant development for customers. It reflects how Dynamics 365 Contact Center helps organizations innovate faster and reduce costs with Microsoft’s unified cloud platform, low-code tools, and built-in AI – making it easier to build, manage, and scale contact center solutions without complex infrastructure or costly custom development.
Teams Phone extensibility enables organizations to unify calling and contact center experiences for both agents and customers, all within a secure, familiar Microsoft environment.
A commissioned Total Economic Impact™ study conducted by Forrester Consulting found that organizations using Teams Phone extensibility with Dynamics 365 Contact Center could achieve a projected return on investment up to 345% over three years2. These savings stem from lower operational and service fees, streamlined administration, and greater call center efficiency.
