Dynamic gateways learn the IP address from SIP registration &#8211; the gateway device registers to VOS3000, and VOS3000 uses the registered IP for routing. Use Static when the vendor has a fixed IP, and Dynamic when the device may have a changing IP or is behind NAT.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"how-do-i-configure-a-gateway-for-a-vendor-that-requires-outbound-registration\">How do I configure a gateway for a vendor that requires outbound registration?<\/h3>\n\n\n\n<p>First, create an entry in Registration Management with the vendor&#8217;s server IP, username, and password. Then create a Routing Gateway with type &#8220;Registration&#8221; and reference the Mark field from Registration Management. VOS3000 will register to the vendor and use that registration for routing calls.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"what-should-the-line-limit-be-set-to\">What should the Line Limit be set to?<\/h3>\n\n\n\n<p>Line Limit should match your agreement with the vendor or the actual capacity of the gateway. Setting it too high may result in call failures when the vendor cannot handle the load. Setting it too low wastes available capacity. Monitor ASR and ACD to determine optimal settings.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"how-do-i-implement-gateway-failover\">How do I implement gateway failover?<\/h3>\n\n\n\n<p>Configure multiple routing gateways with the same prefix but different priorities. Lower priority values are tried first. If a call fails, VOS3000 will try the next gateway in priority order. You can also use Gateway Groups to organize failover paths.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"why-is-my-gateway-showing-as-offline-in-vos-3000\">Why is my gateway showing as offline in VOS3000?<\/h3>\n\n\n\n<p>For dynamic gateways, check if registration is working properly by examining Registration Management. For static gateways, verify the IP is reachable (ping test), firewall rules allow the SIP port, and the gateway device is powered on and operational. Check system logs for registration or connection errors.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"\ud83d\udcde-get-expert-help-with-vos-3000-gateway-configuration\">\ud83d\udcde Get Expert Help with VOS3000 Gateway Configuration<\/h2>\n\n\n\n<p>Need assistance configuring VOS3000 gateways for your wholesale VoIP operation?
