Microsoft Teams Phone

Microsoft's cloud PBX capability for Teams that provides calling, call control and PSTN connectivity options.

Definition

Teams Phone (formerly Phone System) provides features such as call transfer, hold, call park, delegation, voicemail, auto attendants and call queues. Users need a Teams Phone license plus a PSTN option: Microsoft Calling Plans, Operator Connect, Teams Phone Mobile or Direct Routing. Phone numbers are assigned in the Teams admin center or with PowerShell.

Example

Set-CsPhoneNumberAssignment -Identity user@contoso.com -PhoneNumber +14255550100 -PhoneNumberType DirectRouting assigns a number.

Exam tip

Teams Phone alone does not give PSTN access; a PSTN connectivity option is also required.
