About Microsoft 365

byon SBC infrastructure

byon operates its own redundant session border controller (SBC) infrastructure in German data centres. This forms the technical interface between Microsoft Teams and the public telephone network.

The SBC ensures a clear separation between internal and external networks and handles key tasks such as encryption, routing and protocol adaptation. This enhances security, stability and voice quality during operation.

By operating its own infrastructure, byon can flexibly manage telephony and support additional scenarios such as customised numbering logic or the integration of further systems.
