🖥️ Componentes de la Arquitectura de Recuperacion

La arquitectura del sistema VOS3000 recuperacion desastres se compone de tres elementos principales que trabajan en conjunto: el Disaster Tolerance Status, el Disaster Tolerance Data y el Disaster Tolerance Equipment. Cada componente cumple una funcion especifica en la cadena de proteccion que garantiza la continuidad del servicio VoIP ante cualquier tipo de fallo.

El Disaster Tolerance Status muestra en tiempo real el estado de la conexion entre el servidor maestro y el servidor esclavo. Este componente permite al administrador verificar que la sincronizacion esta funcionando correctamente y que el servidor de respaldo esta listo para asumir el control si es necesario. El modulo de recuperacion utiliza este monitor para alertar al administrador cuando la sincronizacion se interrumpe o cuando el servidor esclavo no esta disponible.

💾 Disaster Tolerance Data: Sincronizacion de Datos

La sincronizacion de datos es el proceso mas critico del sistema VOS3000 recuperacion desastres porque determina que informacion estara disponible en el servidor esclavo cuando asuma el control. El sistema replica continuamente los datos del maestro al esclavo, incluyendo configuraciones de pasarelas, tarifas, cuentas de usuarios, reglas de enrutamiento, parametros del sistema y registros de llamadas. Esta replicacion asegura que el servidor esclavo tenga una copia actualizada de toda la informacion necesaria para operar el softswitch.

El proceso de sincronizacion en el sistema VOS3000 recuperacion desastres funciona de manera continua y automatica. Cada cambio realizado en el servidor maestro se propaga al servidor esclavo en tiempo real o near-real-time, dependiendo del tipo de dato. Las configuraciones criticas como pasarelas y rutas se sincronizan inmediatamente, mientras que los CDR pueden tener una sincronizacion con breve retardo. El administrador puede verificar el estado de la sincronizacion desde Disaster Tolerance Data para confirmar que ambos servidores estan alineados correctamente.

🖥️ Disaster Tolerance Equipment: Maestro y Esclavo

La configuracion de los equipos es el componente fisico del sistema VOS3000 recuperacion desastres. Segun el manual oficial, la implementacion requiere dos servidores independientes con el software VOS3000 instalado y el modulo de hot standby activo en ambos. El servidor maestro es el que procesa activamente las llamadas, mientras que el servidor esclavo permanece en modo espera, recibiendo sincronizacion de datos y monitoreando la salud del maestro.

La configuracion del Disaster Tolerance Equipment en el sistema VOS3000 recuperacion desastres requiere que ambos servidores tengan conectividad de red estable entre si. La comunicacion entre maestro y esclavo se realiza a traves de un canal dedicado que transmite los datos de sincronizacion y los heartbeats de monitoreo. Es recomendable que ambos servidores esten en ubicaciones fisicas diferentes para proteger contra desastres que afecten todo un datacenter, como incendios, inundaciones o cortes de energia prolongados.

🔄 Proceso de Takeover Automatico

El takeover automatico es la funcion mas importante del sistema VOS3000 recuperacion desastres porque es el mecanismo que garantiza la continuidad del servicio cuando el servidor maestro falla. El proceso comienza cuando el servidor esclavo detecta que el maestro ha dejado de responder a los heartbeats. Tras un periodo configurable de intentos fallidos, el esclavo determina que el maestro esta fuera de servicio y ejecuta automaticamente el procedimiento de takeover.

Durante el takeover en el sistema VOS3000 recuperacion desastres, el servidor esclavo asume todas las funciones del maestro. Las pasarelas SIP se reconectan automaticamente al nuevo servidor, las llamadas nuevas comienzan a procesarse de inmediato y las sesiones activas se restablecen segun la configuracion. El tiempo de recuperacion depende de la velocidad de deteccion del fallo y la reconexion de las pasarelas, pero generalmente se completa en segundos o minutos, minimizando el impacto en el servicio.

🔄 Escenarios de Recuperacion

La recuperacion de desastres esta disenada para manejar multiples escenarios de fallo, desde la caida completa del servidor maestro hasta problemas parciales de sincronizacion. Comprender estos escenarios es fundamental para prepararse adecuadamente y responder de manera eficiente cuando se presente una situacion de emergencia. Para informacion sobre backup de datos, consulte mantenimiento de datos VOS3000. Sistema VOS3000 Recuperacion

🖥️ Fallo Completo del Maestro

Cuando el servidor maestro falla completamente, el proceso de takeover es automatico. El servidor esclavo detecta la ausencia de heartbeats, verifica que el maestro esta caido y ejecuta el procedimiento de activacion. Las pasarelas SIP se reconectan al nuevo servidor y el servicio se restablece sin intervencion manual. Este es el escenario principal para el que fue disenado el modulo de hot standby.

🌐 Fallo de Red Parcial

Si la red entre el maestro y el esclavo se interrumpe temporalmente sin que el maestro este realmente caido, el sistema puede interpretarlo como un fallo del maestro y ejecutar un takeover innecesario. Para evitar esto, el heartbeat utiliza mecanismos de verificacion multiple antes de ejecutar el takeover, incluyendo verificacion por canales alternativos si estan disponibles. La configuracion del timeout de heartbeat es critica para balancear la velocidad de deteccion con la prevencion de takeovers falsos.

💾 Fallo de Sincronizacion

Si la sincronizacion de datos se interrumpe temporalmente, el servidor esclavo puede tener datos desactualizados. Cuando la sincronizacion se restablece, el sistema realiza una resincronizacion completa para alinear ambos servidores. Durante este periodo, el esclavo puede no estar listo para un takeover correcto, por lo que es importante monitorear el estado de sincronizacion y resolver los problemas de red lo antes posible.

📊 Consideraciones de Licenciamiento

La implementacion del sistema VOS3000 recuperacion desastres requiere licenciamiento adecuado del modulo de Hot Standby. Segun el manual oficial, se necesitan dos copias del software VOS3000, una para el servidor maestro y otra para el esclavo. Ademas, el modulo de Hot Standby debe estar activo en ambas licencias. Las licencias de standby generalmente tienen un costo menor que las licencias de produccion completas, ya que el servidor esclavo no procesa llamadas activamente mientras el maestro esta en funcionamiento. (Sistema VOS3000 Recuperacion)

Es importante verificar que ambas licencias del sistema VOS3000 recuperacion desastres soporten la misma capacidad de llamadas simultaneas para que el servidor esclavo pueda manejar el mismo volumen de trafico que el maestro durante un takeover. Si la licencia del esclavo tiene menor capacidad, el sistema experimentara degradacion de servicio durante el failover. Para informacion sobre la descarga del software, visite vos3000.com.

❓ Preguntas Frecuentes sobre el Sistema VOS3000 Recuperacion Desastres

❓ Que es el hot standby en el sistema VOS3000 recuperacion desastres?

El hot standby es la arquitectura donde un servidor esclavo permanece activo y sincronizado con el servidor maestro, listo para asumir el control de forma inmediata si el maestro falla. A diferencia del cold standby donde el servidor de respaldo esta apagado y requiere arranque manual, el hot standby garantiza una recuperacion rapida porque el esclavo ya tiene los datos actualizados y los servicios listos para activarse en segundos tras detectar el fallo del maestro.

❓ Cuantas copias de VOS3000 se necesitan para el sistema VOS3000 recuperacion desastres?

Segun el manual oficial seccion 2.15, se necesitan exactamente dos copias del software VOS3000 para implementar la recuperacion de desastres. Una copia se instala en el servidor maestro que procesa las llamadas activamente, y la otra copia se instala en el servidor esclavo que permanece en modo standby. Ademas, el modulo de Hot Standby debe estar habilitado en ambas licencias para que la sincronizacion y el takeover automatico funcionen correctamente.

❓ Como se detecta el fallo del maestro en el sistema VOS3000 recuperacion desastres?

El sistema detecta el fallo del maestro mediante el mecanismo de heartbeat. El servidor maestro envia periodicamente senales de latido al servidor esclavo a traves de la red dedicada. Si el esclavo deja de recibir estos heartbeats durante un periodo configurable, determina que el maestro ha fallado y ejecuta automaticamente el procedimiento de takeover. El timeout de heartbeat debe configurarse cuidadosamente para evitar takeovers falsos causados por congestion de red temporal.

❓ Que datos se sincronizan entre maestro y esclavo?

El sistema sincroniza todos los datos criticos del softswitch incluyendo configuraciones de pasarelas SIP, tarifas y codigos de tarifa, cuentas de usuarios, reglas de enrutamiento, parametros del sistema, configuracion IVR y registros CDR. Los datos de configuracion se sincronizan en tiempo real, mientras que los CDR pueden tener una sincronizacion near-real-time con breve retardo. Esta replicacion asegura que el servidor esclavo tenga toda la informacion necesaria para operar correctamente tras un takeover.

❓ Cuanto tiempo tarda el takeover en el sistema VOS3000 recuperacion desastres?

El tiempo de takeover depende de varios factores incluyendo la velocidad de deteccion del fallo, la verificacion de caida del maestro y la reconexion de las pasarelas SIP al nuevo servidor. En condiciones normales, el proceso completo puede completarse entre 30 segundos y 2 minutos. La deteccion del fallo toma entre 10 y 30 segundos, la activacion del esclavo toma 1 a 5 segundos, y la reconexion de las pasarelas puede tomar entre 10 y 60 segundos adicionales segun la configuracion de los gateways.

❓ Es posible ubicar el maestro y el esclavo en diferentes datacenters?

Si, es posible y de hecho se recomienda ubicar los servidores en datacenters diferentes para proteger contra desastres que afecten toda una ubicacion fisica como incendios, inundaciones o cortes de energia prolongados. La unica consideracion es que la latencia de red entre ambos datacenters debe ser lo suficientemente baja para permitir una sincronizacion de datos eficiente y heartbeats rapidos. Una latencia de red inferior a 10 milisegundos es ideal para la operacion correcta del modulo de hot standby.

❓ Que sucede con las llamadas activas durante el takeover?

Las llamadas que estaban activas en el momento del fallo del maestro se perderan porque el servidor maestro ya no esta procesandolas. Sin embargo, una vez que el esclavo asume el control, las llamadas nuevas se procesan normalmente. Para minimizar el impacto en los usuarios, las pasarelas deben configurarse con mecanismos de reconexion automatica que permitan a los usuarios reestablecer sus llamadas rapidamente despues del takeover. La duracion de la interrupcion es tipicamente breve y la mayoria de los usuarios puede reintentar su llamada de inmediato.

El sistema VOS3000 recuperacion desastres proporciona la tranquilidad que todo operador VoIP necesita para garantizar la continuidad del servicio. Desde la configuracion de servidores maestro y esclavo hasta la sincronizacion continua de datos y el takeover automatico, cada componente esta disenado para proteger contra interrupciones no planificadas.

VOS3000 High Availability and Load Balancing Setup Easy Guide

Easy Guide to VOS3000 High Availability and Load Balancing Setup

VOS3000 High availability represents a critical requirement for telecommunications service providers who must maintain continuous operation to meet customer expectations and contractual service level agreements. The VOS3000 softswitch platform provides comprehensive high availability capabilities through master-slave server architecture, automatic failover mechanisms, and sophisticated load balancing features that distribute traffic across multiple processing nodes.

Understanding how to properly configure and maintain these capabilities is essential for building resilient VoIP networks that can withstand hardware failures, software issues, and unexpected traffic spikes without service interruption. VOS3000 High Availability

📌 Understanding High Availability Architecture

The VOS3000 high availability architecture operates on a primary-backup model where a master server handles active call processing while one or more slave servers maintain synchronized copies of configuration and runtime data. The synchronization process continuously replicates database changes, registration information, and operational state from the master to slave nodes. VOS3000 High Availability

For disaster recovery planning, see our comprehensive guide on VOS3000 Disaster Recovery.

🔧 Master-Slave Server Configuration

The master-slave configuration in VOS3000 establishes the foundation for high availability operation:

🔹 Master Server Role

  • Handles all active call processing and routing decisions
  • Maintains the primary database with all write operations
  • Processes all signaling traffic from endpoints
  • Serves as the primary client connection point

🔹 Slave Server Role

  • Operates in standby mode, ready for failover
  • Continuously receives synchronized data from master
  • Monitors master health through heartbeat mechanisms
  • Maintains complete copy of all configuration and billing data

🔹 Server Requirements Matrix

RequirementMaster ServerSlave Server
VOS3000 Version2.1.8.05 / 2.1.9.07Same version as master
Operating SystemCentOS 6/7CentOS 6/7
NetworkStatic IP, low latencySame network preferred
LicenseHA-enabled licenseHA-enabled license

🔄 Failover Mechanisms and Detection

VOS3000 implements multiple detection mechanisms that identify when failover is necessary. The clock deviation alarm monitors the time synchronization between master and slave servers, detecting situations where server clocks drift apart. Accurate time synchronization is critical for proper database replication.

The master synchronize status alarm triggers when host synchronization stops working, indicating potential problems with the master server that may require failover. Similarly, the slave synchronize status alarm monitors the health of backup servers. VOS3000 High Availability

For backup procedures, see our guide on How to Backup Restore VOS3000 MySQL Database.

📊 Gateway Group Load Balancing

Beyond server-level redundancy, VOS3000 provides gateway group capabilities that enable load balancing and redundancy at the termination layer. Gateway groups organize multiple routing gateways into logical collections with defined capacity limits, enabling intelligent distribution of call traffic across multiple termination points.

The line limit parameter at the gateway group level establishes the maximum concurrent calls that can be processed through all gateways in the group collectively. Individual gateway line limits work in conjunction with group limits, ensuring that no single gateway can consume all available group capacity.

🔹 Load Balancing Configuration Example

Gateway GroupTotal Line LimitGateway A LimitGateway B Limit
Group_Premium600400 (Priority 1)200 (Priority 2)
Group_Standard300150 (Priority 1)150 (Priority 1)

For multiple IP configurations, see our guide on Multiple IP License in VOS3000.

🎯 Priority-Based Traffic Distribution

Priority settings on routing gateways provide the primary mechanism for controlling traffic distribution in load balancing scenarios. When multiple gateways are available for a destination, those with lower priority numbers receive traffic first, implementing a preferred routing hierarchy.

VOS3000 enhances this basic priority model with additional factors that influence gateway selection. The ratio of current calls to maximum channels is considered when multiple gateways share the same priority, naturally distributing load across equally-preferred termination points based on available capacity. VOS3000 High Availability

📈 Period Capacity Management

VOS3000 period capacity features enable time-based load balancing configurations that adapt to predictable traffic patterns. The period capacity settings allow gateway line limits to vary based on time of day and day of week, enabling higher capacity during peak traffic hours and reduced capacity during low-traffic periods.

  • Peak Hours (9AM-6PM): Higher capacity allocations
  • Off-Peak Hours (6PM-9AM): Reduced capacity, cost-optimized
  • Weekends: Special routing configurations

Comprehensive monitoring is essential for maintaining high availability, and VOS3000 provides extensive alarm capabilities that detect conditions requiring attention:

Alarm TypeTriggerSeverity
CPU AlarmCPU usage exceeds thresholdMajor/Critical
Memory AlarmMemory usage exceeds thresholdMajor
Database AlarmDatabase errors detectedCritical
Pending CDR AlarmCDR processing backlogMajor
Clock DeviationTime sync issues between serversMajor

💡 Best Practices Summary – VOS3000 High Availability

VOS3000 Architecture & Design: Full Core Components and Call Flow Properly Explained

VOS3000 Architecture & Design: Full Core Components and Call Flow Properly Explained

Understanding VOS3000 architecture is essential for anyone deploying or managing this carrier‑grade softswitch. Whether you’re troubleshooting call failures, planning capacity, or optimizing performance, knowing how the system components interact helps you make better decisions and avoid common pitfalls.

In this comprehensive guide, we’ll break down the VOS3000 architecture into its core modules, explain the end‑to‑end call flow, and give you the knowledge you need to run a stable, scalable VoIP platform.

Core Components of VOS3000 Architecture

The VOS3000 softswitch is built on a modular architecture where each component handles specific functions. Understanding these modules helps you identify where problems occur and how to scale your system effectively.

1. VOS3000 Softswitch Engine

The heart of the system – a high‑performance signaling and control engine that handles:

  • SIP and H.323 signaling processing – registration, invite, bye, etc.
  • Call routing and gateway selection – using longest prefix match, priority, and real‑time metrics (ASR/ACD).
  • Real‑time billing and rating – applies rate cards, checks balances, and manages prepaid/postpaid logic.
  • CDR generation – creates detailed call records for downstream billing and reporting.

2. Media Gateway (MediaProxy)

Manages the RTP (audio) streams between callers and callees. It can operate in different modes depending on your needs: VOS3000 architecture

  • Bypass mode – RTP flows directly between endpoints (lowest latency, minimal CPU load).
  • Proxy mode – Audio passes through VOS3000 for recording, transcoding, or NAT traversal (higher CPU but more features).
  • Mixed mode – System decides automatically based on network conditions and device capabilities.

3. MySQL Database

The persistent storage layer that holds all configuration and historical data:

  • Accounts, rates, and packages – cached in memory for fast access.
  • Gateways and routing rules – defines how calls enter and leave your network.
  • CDR records – partitioned daily (cdr_YYYYMMDD) for performance and easy purging.
  • System logs and alarms – historical events for troubleshooting and auditing.

4. Web Management Interface

An Apache/PHP‑based GUI that allows administrators to configure every aspect of the system – from rate management to user permissions. It communicates with the softswitch engine via internal APIs.

5. VOS3000 Client

A Windows‑based desktop application for real‑time monitoring and advanced configuration tasks that are not available in the web interface (e.g., live call tapping, detailed gateway status).

Understanding Gateway Types in VOS3000

VOS3000 uses two distinct gateway types, and confusing them is a common source of routing errors. Here’s the difference:

Mapping Gateway (Ingress)

Receives calls from upstream providers or customers. Each mapping gateway is linked to a billing account and determines which routing gateways can be used. It also controls caller permissions, black/white lists, and media settings.

Routing Gateway (Egress)

Sends calls out to termination partners. Routing gateways have prefix matching, priority settings, and are linked to clearing accounts for cost tracking. They also handle features like prefix stripping/adding, call duration limits, and failover logic.

VOS3000 Call Flow Architecture (VOS3000 architecture)

Here’s a step‑by‑step breakdown of what happens when a call enters your VOS3000 system:

  1. Incoming INVITE arrives at the softswitch from a mapping gateway (or registered phone).
  2. Authentication – System verifies the gateway IP, checks if the caller is allowed, and validates any digest credentials.
  3. Rate lookup – Using the longest prefix match on the dialed number, the system finds the appropriate rate and checks if the caller is authorized for that call type (local, domestic, international).
  4. Account verification – Checks the linked account’s balance, overdraft limit, and expiry date. If the account uses packages, free minutes are consumed first.
  5. Routing selection – Based on the destination prefix, the system compiles a list of eligible routing gateways, sorts them by priority, ASR, ACD, and current load, then tries them in order until one answers or all fail.
  6. Outgoing call – Softswitch sends an INVITE to the selected routing gateway, applying any configured rewrite rules (caller/callee transformation).
  7. Media path establishment – Depending on media proxy settings, RTP flows directly between endpoints or through the media proxy (for NAT, recording, or transcoding).
  8. CDR generation – After call termination, a CDR is written to the database and made available for real‑time reports and downstream billing systems.

Database Architecture and Data Management

VOS3000 uses MySQL with a carefully designed schema to handle high traffic volumes. Key points:

CDR Table Partitioning

CDRs are stored in daily tables (e.g., cdr_20250309). This prevents any single table from growing too large, keeps queries fast, and simplifies data purging.

Configuration Caching

Critical configuration (accounts, rates, gateways) is loaded into shared memory at startup and updated dynamically when changes are applied. This ensures real‑time performance without hitting the database on every call.

Auto‑Cleanup Mechanisms

System parameters control how long historical data is retained. Regular cleanup prevents disk space exhaustion and maintains database performance.

High‑Level Design Considerations

  • Separate signaling and media – For high‑traffic deployments, run the softswitch engine and media proxy on separate servers to distribute load.
  • Database replication – Implement master‑slave replication to protect against data loss and enable quick failover.
  • Network topology – Ensure low latency between all components; RTP jitter and packet loss directly impact call quality.
  • Redundancy – Consider deploying a hot‑standby softswitch for automatic failover (disaster recovery).

Frequently Asked Questions (VOS3000 architecture)

What is the difference between mapping gateway and routing gateway?

Mapping gateways receive calls into the system and are linked to billing accounts. Routing gateways send calls out to termination partners and are linked to clearing accounts for cost tracking. Think of mapping as “who pays you” and routing as “who you pay.”

Does VOS3000 support transcoding?

Yes, VOS3000 supports codec transcoding through the media proxy. Common codecs like G.729, G.711, GSM, and iLBC can be converted. However, transcoding increases CPU usage, so plan capacity accordingly and consider using it only when necessary.

How does VOS3000 handle high concurrent calls?

VOS3000 uses an event‑driven architecture that can handle thousands of concurrent calls on properly sized hardware. Key factors are CPU speed for signaling, RAM for caching (accounts/routes), and network bandwidth for RTP. Separating media proxy onto dedicated hardware further increases capacity.

Can I run VOS3000 on a virtual machine?

Yes, VOS3000 runs well on virtualized environments (VMware, KVM, Hyper‑V) for moderate traffic loads. For carrier‑grade traffic (500+ concurrent calls), bare metal is recommended to avoid CPU steal time and network latency introduced by hypervisors.

Conclusion

Understanding VOS3000 architecture helps you deploy more stable platforms, troubleshoot faster, and scale effectively. Whether you’re running a small operation or a carrier‑grade service, knowing how the components fit together is essential for long‑term success.

VOS3000 Disaster Recovery & Backup Setup: Master‑Slave High Availability Important Guide

VOS3000 Disaster Recovery & Backup Setup: Master‑Slave High Availability Important Guide

In the VoIP business, downtime means lost revenue and angry customers. A proper VOS3000 disaster recovery plan ensures that your softswitch keeps running even if the primary server fails. Whether you’re serving hundreds or thousands of concurrent calls, a master‑slave high availability (HA) setup is the industry standard for reliability.

In this guide, we’ll walk you through the complete process of configuring VOS3000 disaster recovery, including prerequisites, step‑by‑step setup, testing, and best practices.

Why VOS3000 Disaster Recovery Matters

VOS3000 stores all critical data – accounts, rates, CDRs – in a MySQL database. If the server crashes, you lose not only current calls but also the ability to route new traffic. A disaster recovery setup provides:

  • Automatic failover – slave takes over within seconds
  • Data redundancy – real‑time replication prevents data loss
  • Minimal manual intervention – no need to reconfigure everything

Understanding VOS3000 High Availability Architecture

VOS3000 uses a master‑slave replication model:

  • Master server – handles all live calls, writes CDRs, and accepts configuration changes.
  • Slave server – constantly synchronizes data from the master and stands ready to take over.
  • Shared virtual IP – clients and gateways connect to a single IP that floats between servers.

When the master fails, the slave detects the outage, activates its softswitch services, and assumes the virtual IP. Calls in progress may drop, but new calls are processed immediately.

Prerequisites for Disaster Recovery Setup

Before you begin, ensure you have:

  • Two identical servers with VOS3000 installed (same version, same CentOS/RHEL release).
  • Dedicated private network between them for replication (low latency).
  • Same MySQL root password on both servers.
  • Virtual IP that can be moved between servers (requires `keepalived` or similar).
  • Sufficient disk space on both servers (mirroring CDR storage).

Step‑by‑Step VOS3000 Disaster Recovery Configuration

Step 1: Prepare the Master Server

On the master server, enable binary logging and set a unique server ID:

# Edit /etc/my.cnf

[mysqld]

log-bin=mysql-bin server-id=1 binlog-do-db=vos3000db # your actual database name

Restart MySQL and create a replication user:

CREATE USER 'replica'@'slave_ip' IDENTIFIED BY 'strong_password';
GRANT REPLICATION SLAVE ON *.* TO 'replica'@'slave_ip';
FLUSH PRIVILEGES;

Record the master status:

SHOW MASTER STATUS;

Step 2: Prepare the Slave Server

Stop MySQL, copy the master data to slave (using `mysqldump` or `xtrabackup`), then configure slave:

[mysqld]
server-id=2
relay-log=relay-log

Start MySQL and set up replication:

CHANGE MASTER TO
  MASTER_HOST='master_ip',
  MASTER_USER='replica',
  MASTER_PASSWORD='strong_password',
  MASTER_LOG_FILE='mysql-bin.xxxxxx',
  MASTER_LOG_POS=xxxx;
START SLAVE;

Verify with SHOW SLAVE STATUS\G – both Slave_IO_Running and Slave_SQL_Running should be “Yes”.

Step 3: Configure Virtual IP with Keepalived

Install and configure keepalived on both servers. Example `/etc/keepalived/keepalived.conf` (master):

vrrp_instance VI_1 {
    state MASTER
    interface eth0
    virtual_router_id 51
    priority 101
    advert_int 1
    virtual_ipaddress {
        192.168.1.100/24   # your virtual IP
    }
}

On slave, change state to BACKUP and priority to 100. Restart keepalived.

Step 4: Configure VOS3000 Services for HA

On both servers, ensure that VOS3000 listens on the virtual IP (edit network settings or use IP aliasing). In the VOS3000 web interface, set the “Local IP” of gateways and phones to the virtual IP. This way, after failover, devices reconnect automatically.

Step 5: Test Failover

Simulate a master failure by stopping the master server or the VOS3000 process. Verify that:

  • The virtual IP moves to the slave.
  • New calls can be established.
  • CDRs are written on the slave (and later synced back when master recovers).

Monitoring Disaster Recovery Status

VOS3000 provides built‑in tools to monitor HA status:

  • Disaster Tolerance Status – shows current master, slave, and sync lag.
  • Disaster Tolerance Data – verify data consistency between servers.
  • Disaster Tolerance Equipment – manage registered HA pairs.

Access these via the web interface under “Disaster Recovery System”.

Backup Strategy in a DR Setup

Even with replication, you need regular backups:

  • Daily mysqldump of the entire database (compressed, stored off‑server).
  • Binary logs – keep them for point‑in‑time recovery.
  • Configuration files – backup `/etc` and VOS3000 config directories.

Common Pitfalls and Solutions

  • Replication lag – caused by slow network or heavy writes. Monitor with `Seconds_Behind_Master`.
  • Split‑brain – both servers think they are master. Use fencing (STONITH) or careful keepalived config.
  • Different MySQL versions – always use the same version on both servers.
  • Firewall blocking replication port (3306) – open between servers.

Frequently Asked Questions (VOS3000 Disaster Recovery)

Does VOS3000 support active‑active clustering?

No, VOS3000 officially supports active‑passive master‑slave replication. Active‑active is not recommended because of potential conflicts in real‑time billing and CDR sequence.

How long does failover take?

With keepalived and properly tuned services, failover typically completes within 5‑10 seconds. Calls established before failure may drop, but new calls are processed immediately.

Will I lose CDRs during failover?

If replication is synchronous enough, most CDRs are already on the slave. Any CDRs that were in memory but not yet written to the master’s database may be lost. To minimize loss, set `sync_binlog=1` and `innodb_flush_log_at_trx_commit=1` on master.

Can I use a different hardware for slave?

Yes, but it’s recommended to use identical hardware to ensure consistent performance during failover. If the slave is weaker, it may struggle to handle full traffic load.

How do I switch back to the original master after repair?

Repair the master, ensure it has caught up with the slave (re‑sync if needed), then manually promote it back using a controlled switchover procedure to avoid split‑brain.

Conclusion

Implementing VOS3000 disaster recovery with master‑slave replication is the best way to protect your VoIP business from unexpected outages. While the setup requires careful planning, the peace of mind and service continuity are well worth the effort.
