Make and receive normal business calls in Teams.
Use Microsoft Teams as the user experience while Realtime provides the business numbers, SIP connectivity and calling side of the solution. Ribbon SBC options can provide the certified Direct Routing edge where that model is appropriate.
Teams on the screen. Realtime on the calling side.
Teams Phone licensing
Your Microsoft environment needs the appropriate Teams Phone licensing for voice.
Realtime calling
We provide business numbers, SIP connectivity and PSTN calling to connect Teams to the public telephone network.
Ribbon SBC / Direct Routing
Where Direct Routing is used, a Microsoft-certified SBC provides the secure bridge between Teams and the telephony network.
Numbers & call flows
We plan users, numbers, auto attendants, queues, opening hours, routing and migration from the current phone system.
Direct Routing can connect Teams to Realtime SIP and calling.
Microsoft Direct Routing uses a certified Session Border Controller to connect Teams Phone to a chosen telecommunications provider or existing telephony environment. Ribbon provides certified SBC options that can run in the cloud, as virtual software or on dedicated appliances.
That can also support staged migrations where Teams and an existing PBX need to coexist rather than switching every user at once.
