Q:

Powershell Active Directory Attributes Creating User

My code:
New-ADUser -samaccountname first_last -Name "first last" -UserPrincipalName aaa@egc.gov.vm -AccountPassword (ConvertTo-SecureString -AsPlainText "p@ssw0rd" -Force) -Enabled $true -PasswordNeverExpires $true -Path 'OU=EGC,DC=egc,DC=gov,DC=vm' -givenname 'first' -sn 'last' -displayname 'display name' -description 'IC NO' -title 'Job Title' -division '3' -physicaldeliveryofficename 'EGNC HQ' -telephonenumber '2424955' -mail 'first.last@egc.gov.bn' -department 'egnc hq' -company 'ministry PMO' -streetaddress 'Full Address Here' -postalcode 'BB3333'

One of the Error: 
New-ADUser : A parameter cannot be found that matches parameter name 'telephonenumber'. 

The error follows the the following LDAP attributes:

sn
physicalDeliveryOfficeName
telephonenumber
mail

User creation works if I remove the mentioned attributes. 
Any fix for this?

sn is Surname
telephonenumber is officephone (Thanks to David Johnson)
physicalDeliveryOfficeName is office (Thanks to David Johnson)
mail is email
