\u2013 too short causes failures, too long wastes resources.<\/li>\n\n\n\n<li><strong>Monitor call logs<\/strong> after changes to detect unintended consequences.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"frequently-asked-questions\">Frequently Asked Questions (VOS3000 System Parameters)<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"do-i-need-to-restart-vos-3000-after-changing-parameters\">Do I need to restart VOS3000 after changing parameters?<\/h3>\n\n\n\n<p>No. VOS3000 reads parameters from the database in real time. Changes take effect immediately for new calls. Ongoing calls continue with the parameters they started with.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"can-i-break-my-system-by-changing-a-parameter\">Can I break my system by changing a parameter?<\/h3>\n\n\n\n<p>Most parameters are safe to experiment with, but extreme values (e.g., setting timeouts to 0) can cause unexpected behavior. Always note the original value so you can revert if needed.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"whats-the-most-important-parameter-for-reducing-call-failures\">What&#8217;s the most important parameter for reducing call failures?<\/h3>\n\n\n\n<p>For SIP, start with <code>SS_SIP_TIMEOUT_INVITE<\/code> and <code>SS_SIP_RESEND_INTERVAL<\/code>. If carriers are slow to respond, increasing these can reduce &#8220;Response timeout&#8221; failures.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"how-do-i-enable-nat-keep-alive-for-sip-devices\">How do I enable NAT keep\u2011alive for SIP devices?<\/h3>\n\n\n\n<p>Set <code>SS_SIP_NAT_KEEP_ALIVE_PERIOD<\/code> to 20\u201130 seconds and <code>SS_SIP_NAT_KEEP_ALIVE_MESSAGE<\/code> to &#8220;HELLO&#8221; or any string. The softswitch will send UDP packets to keep NAT bindings open.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"what-does-ss-mediaproxymode-auto-actually-do\">What does &#8220;SS_MEDIAPROXYMODE = Auto&#8221; actually do?<\/h3>\n\n\n\n<p>Auto mode enables media proxy only when needed \u2013 e.g., when devices are behind different NATs, when encryption is required, or when a device explicitly requests it. This is the recommended setting for most deployments.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"conclusion\">Conclusion<\/h2>\n\n\n\n<p>Mastering <strong>VOS3000 system parameters<\/strong> gives you fine\u2011grained control over your softswitch. Use this reference as a starting point, experiment carefully, and always monitor the impact of your changes. With the right tuning, you can maximize call completion rates, improve voice quality, and optimize resource usage.<\/p>\n\n\n\n<p>Need expert help with VOS3000 configuration or performance tuning?
