Nemertes Direct Routing Buyer’s Guide

Microsoft Teams users have two options for connecting to the Public Switched Telephone Network (PSTN): Microsoft Teams Calling Plan and Direct Routing. The latter allows enterprises to connect their own session border controller (SBC) to Microsoft Teams, enabling them to choose their own SIP Trunking and E911 provider. Benefits of Direct Routing include cost savings, improved control and flexibility, faster migration to Teams, support for PSTN connectivity during migration or in a hybrid model, access to advanced porting capabilities, and the ability to use emerging features offered by some providers. When selecting a SIP Trunking provider, consider network ownership and connectivity, scale and reach, pricing, reliability, network connectivity options, E911 support, and advanced services. Other factors to consider include Microsoft certified SBC option, migration options, E911 regulatory requirements, flexible billing models, and certification for Microsoft Teams.
