Navigate to Number Management &gt; Black\/White List Group, create a new group with a descriptive name, add the number to block, then apply the group to your gateway or phone.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"what-is-the-difference-between-system-white-list-and-black-white-list-groups\">What is the difference between System White List and Black\/White List Groups?<\/h3>\n\n\n\n<p>The System White List operates at the highest priority level, guaranteeing that listed numbers can never be blocked by any filtering mechanism. It is used for numbers that must always have access. Black\/White List Groups are applied at the entity level (gateway or phone) and can be used for both allowing and blocking numbers based on business rules.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"how-do-i-remove-a-number-from-the-dynamic-black-list\">How do I remove a number from the Dynamic Black List?<\/h3>\n\n\n\n<p>To remove a number from the Dynamic Black List in VOS3000 number management, navigate to Number Management &gt; Dynamic Black List, locate the entry you want to remove, and use the delete function to unblock the number immediately. Consider adding frequently blocked legitimate numbers to the System White List to prevent recurring blocks.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"can-i-use-wildcards-in-black-white-list-groups\">Can I use wildcards in Black\/White List Groups?<\/h3>\n\n\n\n<p>Black\/White List Groups in VOS3000 number management use full match mode, requiring exact number correspondence. Wildcard patterns (* and ?) are not supported in list group entries. If you need pattern-based filtering, consider using number transformation rules or gateway-level filtering options.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"how-do-i-configure-area-based-routing-using-area-information\">How do I configure area-based routing using Area Information?<\/h3>\n\n\n\n<p>Area Information provides geographic context for numbers, but routing decisions are made through rate and routing configuration. Configure Area Information prefixes to identify destinations, then use rate management functions to define rates for each prefix, and configure routing to select appropriate gateways for each destination.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"where-can-i-get-help-with-vos-3000-number-management-configuration\">Where can I get help with VOS3000 number management configuration?<\/h3>\n\n\n\n<p>MultaHost provides comprehensive technical support for VOS3000 number management configuration.
