VOS3000 Installation Process

The installation package includes all required services: SIP server, database schema, web manager, and core billing components. After installation, administrators must verify service status and initial configuration.

Once installed, routing and billing must be configured. Refer to the detailed VOS3000 routing configuration guide to complete call flow setup.

Upgrading VOS3000 Versions

VOS3000 supports in-place upgrades between compatible versions, such as from 2.1.6.x to 2.1.8.x. Before upgrading, always back up:

Database (CDR, rates, users)

Configuration files

Patch Management

Minor patches address performance improvements and bug fixes. Patches should be applied during low-traffic windows and verified through test calls.

Rollback Strategy

If an upgrade introduces unexpected behavior, a rollback plan ensures rapid service restoration. Rollback typically involves restoring the previous database snapshot and configuration files.

Post-Installation Validation

Test inbound and outbound calls

Verify CDR generation (see VOS3000 billing configuration)
