Bringing PSTN calling to Teams options Ø Buy everything from Microsoft More expensive than UCaaS, program users, self support, 99.9% SLA only with desk phones, and number porting (must be wired and using MS certified phone) Ø DIY Direct Routing Purchase, program & maintain all SBCs, purchase & manage SIP trunks, E911. Administrate via PowerShell Ø Managed Direct Routing (with/without bundled PBX) Monthly fee for managed PSTN access, E911, user programming, and PBX support. Some PowerShell skills needed for implementation and ongoing management Ø Operator Connect Similar to Managed Direct Routing,customer chooses an Operator from Teams Admin Center. Operator owns/maintains PSTN integration to MSFT Cloud. Use Teams Admin Center vs. PowerShell. Analog device limitations Ø Embedded Dialer App download to Teams client, No need for MSFT Phone licensing, call path stays with UCaaS provider, soft phone overlaid into Teams.
