If you are talking about the Sterling Correctional Facility in the Colorado Department of Corrections, the correct and only choice is OffenderConnect.com. Their rates are the same price for all calls whether you are in Sterling CO or anywhere in the United States. Set up and fund an AdvancePay account. You will not need a different phone line from InmateAid or anyone else... for this situation.
