Voice on Teams

Integrate and connect your Microsoft Teams business environment to Belcenter’s communication network. When you use the Teams environment, you benefit from the integration with your colleagues and contacts, but you don’t have the dial-in/out functionality.

Belcenter offers you full integration thanks to the Teams application or with physical devices such as telephones, webcams or other integrated systems for your meeting rooms.
To be able to offer this functionality and achieve a perfect integration, a Business Voice or Phone System licence is required, as well as a licence for SBC Hosted Voice.
These licences are invoiced per user and are completely flexible for your organisation. You choose which users have access to these advanced functionalities.
- The Business Voice or Phone System licence activates the advanced functionalities in the Microsoft environment.
- The SBC Hosted Voice licence provides redundant infrastructure on several data centres, so as to establish a secure connection between Microsoft and Belcenter’s network.
Once this integration is complete, we perform the routing of your telephone numbers to your Microsoft environment via the direct connectivity between our network and Microsoft.
Choosing integration with Belcenter’s network means ensuring you have local support, a guarantee that your outgoing calls will be routed correctly and direct management of your incoming traffic, while benefiting from the advanced functionalities of Teams.

Testimonial
“Our company, Peruweld, specializes in the industrial manufacturing of tanks, silos and all kinds of industrial process apparatus. Our activity requires a permanent Internet connection in order to facilitate our communication with our clients, including the likes of Bayer, Total and BASF.
This prompted us to move our applications to the cloud. The criticality of our applications meant that we had to find an ultra-professional and high-performance access provider. That’s in 2007 why we chose to collaborate with Belcenter, who were offering very demanding SLA contracts. And we genuinely do not regret it. To give you an example, when there was a general incident throughout the local area a few years ago, technicians were on site within two hours to lay a temporary cable (purely for us) from the VDSL street-cabinet to our IT room.”
