The arbitrage

Calling Plans charge per user — costs scale linearly with headcount. Direct Routing uses shared SIP trunks — costs stay flat as you grow.

A 5,000-user enterprise on Calling Plans pays $480K–$900K annually on top of Teams Phone Standard. After migration to Direct Routing, trunking costs drop to ~$45K. That's verified, not estimated.

  • Same Teams Phone features
  • Same phone numbers
  • Full SIP trunk control
  • Analog device support (Calling Plans can't do this)
  • Custom routing and dial plans
  • Better E911 control with PIDF-LO
