I tried to make a script to change a phone number in auto attendent teams

Hello,

i want to create a powershell script where i can change the Auto attendant of the teams admin so that users can change the phone number of the after hours without having a teams admin license, does anyone know how i can change the number of the Auto attendants using powershell?

Its in Auto attendants -> your Auto attendant -> Call flow for after hours -> Call routing options - > redirect call -> phone number that i want to change using powershell.

I made a script but it does not seem to work. could someone please tell me what is wrong with it?

# connect with teams

Connect-MicrosoftTeams

# Set up variable

$AutoAttendantId = "3d7ff2b0-1b1e-4bd8-92c3-cb4e3316d6be"

$NewPhoneNumber = "+31625450875"

# Get auto attendant

$AA = Get-CsAutoAttendant -Identity $AutoAttendantId

if (-not $AA) {

    Write-Host "Auto Attendant not found. Please check the ID." -ForegroundColor Red

    Exit

}

# Go to after hours

$AfterHoursCallFlow = $AA.CallFlows | Where-Object { $_.Name -like "*After hours*" }

if (-not $AfterHoursCallFlow) {

    Write-Host "After Hours Call Flow not found. Please check the settings." -ForegroundColor Red

    Exit

}

# go to menu screen of phone number

$AfterHoursCallFlow.CallRouting | ForEach-Object {

    if ($_.Type -eq "PhoneNumber") {

        $_.PhoneNumber = $NewPhoneNumber

    }

}

# Update de Auto Attendant with new settings

Set-CsAutoAttendant -Instance $AA

# Show tekst that its completed

Write-Host "Phone number updated successfully to $NewPhoneNumber" -ForegroundColor Green
