How do I change IP Office to 4 digit extension?

[suprmario]

My extensions are currently 221 and up.
I need to change them into the 7000 and up range.
I've got 4 TCM-8 cards into the base, with 2 analog trunks cards.
I am using IP Office 500 v2, 7.0

within manager click the tools menu and then extension renumber. add the appropriate amount to get the extensions you want. ie if you wanted 7000 as your first extn you would add 6779.
