powershell to edit multiple users phone numbers in active directory - powershell

Question

I am looking to update every user in AD both Telephone numbers from the general tab and pager, mobile and fax. What I am looking to update is any user in our AD from +44 (0) +44 0
I have tried with the following but did not work but can't see why
$UserSplat = #{
LDAPFilter = "(|(homephone=*)(othermobile=*)(mobile=*))"
Properties = #('homephone', 'othermobile', 'mobile')
SearchBase = 'OU=NoAdm,OU=Users,DC=xxxxx,DC=xxxxx,DC=xxxxx,DC=net'
}
Get-ADUser #UserSplat | ForEach-Object {
$CurrentUser = New-Object -TypeName PSCustomObject -Property #{
Name = $_.Name
HomePhone = (-join $_.homephone) -replace '\s'
OtherMobile = (-join $_.othermobile) -replace '\s'
Mobile = (-join $_.mobile) -replace '\s'
}
$CurrentUser
if ($CurrentUser.homephone -notmatch '^\(0)') {
$_ | Set-ADUser -Replace #{homephone = "0$($CurrentUser.HomePhone)" } -WhatIf
}
}

Answer 1

I unfortunately can't test this, I believe -LDAPFilter should be capable of filtering only those users that actually have their homephone, othermobile and mobile attributes starting with +44 (0) hence I added that to save a step. I also left the -WhatIf switch to be sure the script is doing what is supposed to do.
$startsWith = '+44 (0)'
$UserSplat = #{
LDAPFilter = "(|(homephone=$startsWith*)(othermobile=$startsWith*)(mobile=$startsWith*))"
Properties = #('homephone', 'othermobile', 'mobile')
SearchBase = 'OU=NoAdm,OU=Users,DC=xxxxx,DC=xxxxx,DC=xxxxx,DC=net'
}
$startsWith = [regex]::Escape($startsWith)
foreach($user in Get-ADUser #UserSplat)
{
$replaceHash = #{}
foreach($prop in 'homephone', 'othermobile', 'mobile')
{
if(($replace = $user.$prop) -match $startsWith) {
$replaceHash[$prop] = $replace -replace '\(|\)'
}
}
Set-ADUser $user -Replace $replaceHash -WhatIf
}
