Cal. Gov. Code § 77211

Any trial court may establish a “900” telephone number or numbers for traffic, misdemeanor, and other telephonic arraignment, for court scheduling, and for rendering tentative civil decisions, provided the court provides an alternative method of obtaining the service or information in a free and timely manner, and informs individuals of this alternative in the message preceding the “900” information. The proceeds from these “900” telephone numbers shall be continuously and solely appropriated to the use of that court for staff, information, and data-processing services for the purposes specified in this section.
