Take last 4 digits in Business Phone and add to IP Phone atttribute

Question

Hope someone can help. We have all our users 10 digit phone number in Active Directory under the Business Phone. We are integrating our Phone system with AD but want to pull the IP Phone attribute from AD into the phone system. Does anyone know of a way
to look at the users Business Phone attribute and look at the last 4 digits of the number and add it to the ip phone attribute. We are hoping to not have to do this manually for each user.
Thanks,
Gavin

Hi Gavin,
Assuming you're referring to the 'Telephone number' field in ADUC, this will do what you're after:
Get-ADUser -Filter * -SearchBase 'OU=Test 1,DC=domain,DC=com' -Properties OfficePhone | ForEach {
$phoneNumber = $_.OfficePhone.Substring($_.OfficePhone.Length - 4, 4)
Set-ADUser -Identity $_.SamAccountName -Replace @{ipPhone=$phoneNumber}
This will replace the IP Phone field with the last 4 characters present in the telephoneNumber attribute for every user in the targeted OU.
