During business hours, you may want to allow all destinations through a premium gateway. After hours, you may need to block premium-rate numbers and reroute through a cheaper carrier. On weekends, an entirely different dial plan and priority structure may apply. The <strong>VOS3000 period dial plan restriction<\/strong> system provides three powerful per-gateway controls \u2014 Period Dial Plan, Period Call Restriction, and Period Priority \u2014 that allow you to define time-based rules for number transformation, call blocking, and gateway selection order. \ud83d\udd27<\/p>\n\n\n\n<p>\u2699\ufe0f All three features are located under Additional settings &gt; Period control in each routing gateway&#8217;s configuration panel. According to the VOS3000 V2.1.9.07 Manual \u00a72.5.1.1 (pages 37\u201340), the VOS3000 period dial plan restriction system consists of three independent sub-panels: Period Dial Plan (page 37), Period Call Restriction (page 38), and Period Priority (page 40). Each sub-panel uses the same Weekdays \/ Begin time \/ End time framework but applies different rules \u2014 dial plans transform numbers, call restrictions block or allow specific prefixes, and priority changes the gateway&#8217;s selection order. Together, they create a comprehensive VOS3000 period dial plan restriction strategy that adapts to your traffic schedule. \ud83d\udcca<\/p>\n\n\n\n<p>\ud83c\udfaf This guide provides a complete, manual-verified reference for all three VOS3000 period dial plan restriction features.

The VOS3000 period dial plan restriction dial plan applies only during the defined time window and overrides the static dial plan for that period. When the period expires, the static dial plan becomes active again. This allows you to, for example, use one number transformation rule during business hours and a different rule after hours, all on the same gateway.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"\u2753-can-i-use-allow-and-forbidden-operations-together-in-period-call-restriction\">\u2753 Can I use Allow and Forbidden operations together in Period Call Restriction?<\/h3>\n\n\n\n<p>\ud83d\udeab Each VOS3000 period dial plan restriction call restriction entry uses either Allow or Forbidden \u2014 you cannot combine both in a single entry. However, you can create multiple entries for different time periods, using Forbidden during one period and Allow during another. For example, you could create a Forbidden entry for premium prefixes (1900, 09xx) during 18:00\u201309:00 and an Allow entry for all domestic prefixes during 09:00\u201318:00. The VOS3000 period dial plan restriction supports multiple entries to create complex time-based access policies.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"\u2753-how-does-period-priority-affect-the-routing-selection\">\u2753 How does Period Priority affect the routing selection?<\/h3>\n\n\n\n<p>\ud83d\udcca In VOS3000, gateway priority determines the order in which gateways are tried when multiple gateways match a destination prefix. Lower priority numbers are tried first (higher priority). The VOS3000 period dial plan restriction priority feature changes the gateway&#8217;s priority number during the defined period, effectively promoting or demoting the gateway in the selection order. For example, if a gateway has static priority 5 but a period priority of 1 during 00:00\u201308:00, it becomes the first-choice gateway during that time window. This enables cost-optimized routing where cheaper gateways are preferred during off-peak hours.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"\u2753-do-all-three-period-control-features-need-to-be-configured-together\">\u2753 Do all three Period Control features need to be configured together?<\/h3>\n\n\n\n<p>\ud83d\udd27 No, all three VOS3000 period dial plan restriction features are independent. You can configure only Period Dial Plan, only Period Call Restriction, only Period Priority, or any combination. Each feature operates independently based on its own time window configuration. For example, you might use only Period Priority on a gateway to change its selection order during peak hours, without any dial plan changes or call restrictions. The VOS3000 period dial plan restriction system is flexible and allows you to use exactly the features you need.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"\u2753-can-different-gateways-have-different-period-configurations\">\u2753 Can different gateways have different period configurations?<\/h3>\n\n\n\n<p>\ud83d\udce1 Yes, the VOS3000 period dial plan restriction is configured per-gateway. Each routing gateway has its own independent Period Dial Plan, Period Call Restriction, and Period Priority tables. This means Gateway A can have a business-hours dial plan for weekdays while Gateway B has a weekend-only restriction, and Gateway C has a different priority schedule entirely. This per-gateway flexibility in the VOS3000 period dial plan restriction system allows you to design complex, gateway-specific time-based policies. Need help designing your period control strategy?
