PostgreSQL

KubeVoIP requires a PostgreSQL database and a standard connection Secret with host, port, dbname, user, and password.

The operator runs forward database migrations automatically during reconciliation. PostgreSQL stores route data, dial policies, subscriber hashes, registrations, trunk metadata, and digest HA1 values. HA1 is credential-equivalent for its SIP realm.

Use a durable PostgreSQL service for production instead of the quickstart Deployment. Point SIPGateway.spec.databaseSecretRef.name at the Secret for that database.
