Direct Routing works by enabling voice connectivity between your customers and employees through Execulinks ISP-grade access to the PSTN (Public Switched Telephone Network) with the help of a secure, hosted Session Border Controller (SBC).
Certified SBCs are a firewall for VoIP and provide a layer of security and protection from attacks, breaches, and Distributed Denial of Service (DDOS), while providing Quality of Service (QoS) between multiple networks
Unlike other providers, Execulink leverages a geographically redundant SBC network hosted on Canadian soil to connect to a Microsoft Teams PBX.
