  • Global call blocks prevent specific callers, or groups of callers, from reaching any UNLV phones. Global block requests must be submitted to the Telecom Support Desk. The Approving Authority will review all Global requests and approve or deny on a case-by-case basis.

Individuals can dispute blocking decisions by following the Dispute Procedure.

Call blocks will be reviewed on a schedule, outlined in the Call Block Review Procedure, to limit call blocking to active issues.
