Remove periods from Variable

i trying automate enrolling users lync.  the query finds users not lync enabled , gets data user.  $nolync = get-csaduser -ldapfilter "employeenumber=primary" -ou "ou=users,dc=domain,dc=com" | where-object {$_.enabled -eq $null}

so query finds users in users ou of account type primary , not lync enabled.  for user enrolled in lync need telephonenumber attribute not contain periods.  however due how user accounts provisioned, telephone number contain 111.222.3333.  

i need telephonenumber attribute users in $nolync have value 111222333

so in short need query (as did above) go through each user , remove periods telphonenumber attribute, after done, can @ $nolync , see origional query expetion telephonenumber attribute contain no periods or special characters.  

help appreciated.  

sure.

 $nolync = get-csaduser -ldapfilter "employeenumber=primary" -ou "ou=users,dc=domain,dc=com" |    where-object {$_.enabled -eq $null} |   select *     foreach ($csaduser in $nolync)    { $csaduser.telephonenumber = 'tel:+1{0}' -f ($csaduser.telephonenumber -replace '[^\d]') }
