Microsoft Teams

We’ll make sure your telephony integration is set, so you can easily call with Microsoft Teams. We can also integrate Microsoft Teams with our Cloud Telephony solution, providing you with specific telephone exchange functions. Integrate and combine with a worldwide VoIP infrastructure and supplement with specific customization for service desks, call centers, receptions or other Cloud application integrations.



Integrate current VoIP environment with Teams

We integrate your current telephony environment with our Global VoIP (SIP) platform and connect it directly to Microsoft Teams via Direct Routing. For example, with Microsoft Teams you can make and receive calls from anywhere in the world via mobile, landline or computer.


Larger International footprint than Microsoft

Microsoft can deliver its solution in a limited number of countries. We go further and deliver the solution in more countries by combining with our Global VoIP (SIP) solution. In addition, we offer customization to integrate with current solutions, such as telephone exchanges and Cloud telephony or other Cloud applications.

Keep using all phonesystem (PXB) features

Our solution can be used with or without the use of the telephone exchange functions of Microsoft Teams. For specific solutions we combine the solution with our Global VoIP infrastructure and Cloud telephony solutions.

Lower costs with customized rate plans

We offer an all-in tailor-made rate by setting up customer-specific rate plans. In addition, we can provide a total solution with infrastructure based on our Global Connectivity portfolio, SD-WAN and by integrating Microsoft Teams with the existing telephone exchange environment.

The best user experience with SD-WAN

Our SD-WAN solutions offer various techniques to improve Microsoft Teams video and voice sessions in demanding regions. We use various VMware SD-WAN techniques and Voice Quality Management (the first network product to win the Unified Communications Award).

Reception desk solution

We provide a solution for the reception desk which works with Microsoft Teams.
