Phone number escrow porting phone numbers? - business escrow services

I have a few phone numbers of past cases. I do not want to lose the phone numbers, but do not want to pay more to keep the number of assets?

Suggestions on how I can keep the phone number? Is there a service telephone numbers for backup? Is there somewhere you can port the phone numbers for a small monthly fee?
