Hardware failures, network outages, and software issues can all cause service interruptions. VOS3000 disaster recovery functionality addresses these challenges through:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>\u2705 <strong>Automatic Failover:<\/strong> Seamless switch to backup server when primary fails<\/li>\n\n\n\n<li>\u2705 <strong>Data Synchronization:<\/strong> Real-time replication of configuration and CDR data<\/li>\n\n\n\n<li>\u2705 <strong>Business Continuity:<\/strong> Maintained call processing during maintenance windows<\/li>\n\n\n\n<li>\u2705 <strong>Disaster Tolerance:<\/strong> Protection against complete site failures<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"\ud83d\udd27-vos-3000-disaster-recovery-components\">\ud83d\udd27 VOS3000 Disaster Recovery Components<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"\ud83d\udd39-master-server-role\">\ud83d\udd39 Master Server Role<\/h3>\n\n\n\n<p>The master server handles all active call processing, routing decisions, and client connections. It maintains the primary database and handles all write operations. In normal operation, all endpoints register with the master server, and it processes all signaling traffic.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"\ud83d\udd39-slave-server-role\">\ud83d\udd39 Slave Server Role<\/h3>\n\n\n\n<p>The slave server operates in standby mode, continuously receiving synchronized data from the master. It monitors the master&#8217;s health through heartbeat mechanisms and stands ready to assume the master role instantly upon failure detection. The slave maintains a complete copy of all configuration and billing data.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"\ud83d\udd39-data-synchronization-mechanism\">\ud83d\udd39 Data Synchronization Mechanism<\/h3>\n\n\n\n<p>VOS3000 uses MySQL replication combined with application-level synchronization to ensure data consistency between master and slave servers. The synchronization covers:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Account and rate configuration<\/li>\n\n\n\n<li>Gateway and routing settings<\/li>\n\n\n\n<li>CDR records and billing data<\/li>\n\n\n\n<li>System parameters and security settings<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"\ud83d\udcca-prerequisites-for-ha-setup\">\ud83d\udcca Prerequisites for HA Setup<\/h2>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><th>Requirement<\/th><th>Master Server<\/th><th>Slave Server<\/th><\/tr><tr><td>VOS3000 Version<\/td><td>2.1.8.05 \/ 2.1.9.07<\/td><td>Same version as master<\/td><\/tr><tr><td>Operating System<\/td><td>CentOS 6\/7<\/td><td>CentOS 6\/7<\/td><\/tr><tr><td>Network<\/td><td>Static IP, low latency<\/td><td>Same network preferred<\/td><\/tr><tr><td>Hardware<\/td><td>Match production needs<\/td><td>Equal or greater specs<\/td><\/tr><tr><td>License<\/td><td>HA-enabled license<\/td><td>HA-enabled license<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"\u2699\ufe0f-step-by-step-disaster-recovery-configuration\">\u2699\ufe0f Step-by-Step Disaster Recovery Configuration<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"step-1-install-vos-3000-on-both-servers\">Step 1: Install VOS3000 on Both Servers<\/h3>\n\n\n\n<p>Install VOS3000 on both master and slave servers using the same installation package and license. Ensure both servers can communicate over the network on required ports (5060, 5061, database ports).<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"step-2-configure-master-server\">Step 2: Configure Master Server<\/h3>\n\n\n\n<p>On the master server, navigate to Disaster Recovery settings in the VOS3000 client. Enable master mode and configure the following parameters:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Set server role to &#8220;Master&#8221;<\/li>\n\n\n\n<li>Configure slave server IP address<\/li>\n\n\n\n<li>Set synchronization interval (recommended: real-time)<\/li>\n\n\n\n<li>Enable automatic failover detection<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"step-3-configure-slave-server\">Step 3: Configure Slave Server<\/h3>\n\n\n\n<p>On the slave server, configure the disaster recovery settings:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Set server role to &#8220;Slave&#8221;<\/li>\n\n\n\n<li>Enter master server IP address<\/li>\n\n\n\n<li>Configure heartbeat interval<\/li>\n\n\n\n<li>Set failover threshold (recommended: 3 missed heartbeats)<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"step-4-enable-data-synchronization\">Step 4: Enable Data Synchronization<\/h3>\n\n\n\n<p>Configure MySQL replication between the two servers. The master database writes binary logs that the slave reads and applies. Verify synchronization status through the disaster tolerance data page.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"step-5-test-failover\">Step 5: Test Failover<\/h3>\n\n\n\n<p>Perform a controlled failover test by stopping the master server services.
