How would someone from the outside change the call list for the person inside?

You want to change who your inmate may call? That will NEVER happen. You cannot control the inmate's call list, visitation list or how they spend the money they have on their books. Inmates have privacy rights, too. If you do not want an inmate to contact you, you can call the facility and speak to a counselor or case manager - they will see to it that you are not disturbed.
