countries from calling my VOS3000?<\/h3>\n\n\n\n<p>Yes, you can block entire countries by configuring IP-based restrictions for IP ranges assigned to specific countries, and\/or by blocking calls with caller ID prefixes associated with those countries. This requires maintaining up-to-date IP geolocation data and prefix lists.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"how-do-i-know-if-an-ip-is-attempting-fraud\">How do I know if an IP is attempting fraud?<\/h3>\n\n\n\n<p>Monitor for patterns like: multiple failed registration attempts, calls to unusual destinations, sudden spike in call volume, calls at unusual hours, and calls to premium rate numbers. VOS3000&#8217;s dynamic blacklist feature automatically blocks IPs with repeated failed authentication.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"what-destinations-should-i-block-by-default\">What destinations should I block by default?<\/h3>\n\n\n\n<p>Consider blocking: satellite codes (881, 882, 883), premium rate numbers (900 series), known high-fraud regions, and destinations you don&#8217;t do business with. Always balance security with business needs &#8211; over-blocking can reject legitimate calls.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"how-do-ip-restrictions-interact-with-nat\">How do IP restrictions interact with NAT?<\/h3>\n\n\n\n<p>IP restrictions work with the source IP seen by VOS3000. If clients are behind NAT, the restriction applies to the NAT public IP. For accounts behind the same NAT, use account-level credentials rather than IP restrictions alone.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"can-i-whitelist-specific-i-ps-while-blocking-all-others\">Can I whitelist specific IPs while blocking all others?<\/h3>\n\n\n\n<p>Yes. Enable SS_ACCESS_IP_CHECK and configure Access IP fields for each account with only the allowed IP addresses. Calls from any other IP will be rejected even with correct credentials.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"\ud83d\udcde-get-expert-vos-3000-security-support\">\ud83d\udcde Get Expert VOS3000 Security Support<\/h2>\n\n\n\n<p>Need assistance configuring VOS3000 geofencing or implementing fraud prevention?
