microsoft teams direct routing

Microsoft Teams Direct Routing is a configuration that connects Microsoft Teams to the public switched telephone network (PSTN) through a third-party Session Initiation Protocol (SIP) trunk provider. This setup allows organizations to use their existing telephony infrastructure with Teams, enabling features like local-number presence and cost-effective cross-border calling. A recent thread discusses Routercall Communications launching enhanced SIP trunks and a new Teams Direct Routing service in Nigeria, targeting multinational companies, SMEs, and corporate organizations. The service aims to provide cheaper cross-border calling and enterprise voice capabilities within Microsoft 365 workflows, highlighting how business phone systems are integrating with collaboration platforms.
