Powershell for creating a Auto Attendant

Hello @JFM_12, To create a Teams Auto Attendant with New-CsAutoAttendant and redirect calls to an external number, you must define a DefaultCallFlow object that includes a call transfer action.

Here’s how you can do it in PowerShell:

# Define the external number (must be in E.164 format, e.g., +33123456789 for France)

$externalNumber = "+33XXXXXXXXX"

# Create the call transfer action

$transferTarget = New-CsAutoAttendantCallableEntity -Identity $externalNumber -Type ExternalPstn

$callTransferAction = New-CsAutoAttendantCallTransferAction -TransferTarget $transferTarget

# Create the call flow with the transfer action

$defaultCallFlow = New-CsAutoAttendantCallFlow -Name "Default" -Greetings @() -Menu $null -Actions $callTransferAction

# Create the Auto Attendant

New-CsAutoAttendant -Name "xx" `

    -LanguageId "fr-FR" `

    -TimeZoneId "Romance Standard Time" `

    -DefaultCallFlow $defaultCallFlow
