PBX Call Tarifficator Pro

Implementing PBX Call Tarifficator Pro: A Step-by-Step Deployment Guide

1. Project overview

• Goal: Deploy PBX Call Tarifficator Pro to capture CDRs, apply tariffs, generate bills, and export reports for your PBX environment.
• Assumed environment: Linux server (Ubuntu 20.04+ or CentOS 8+), PostgreSQL or MySQL, PBX (Asterisk, FreeSWITCH, 3CX, etc.) producing CDRs, DNS and SMTP available.

2. Pre‑deployment checklist

• System requirements: 4+ CPU cores, 8+ GB RAM, 100+ GB disk (adjust for expected CDR volume).
• Network: Static IP, firewall rules for management ports, PBX access to CDR export endpoint.
• Backups: Configure DB backups and file-system snapshots.
• Credentials: Admin account, DB user, SMTP for invoicing, TLS cert for web UI.

3. Installation steps

1. Provision server: Create VM with chosen Linux distro, update packages.
2. Install dependencies: Web server (NGINX), runtime (Java/Python/Node as required by the product), DB server (Postgres/MySQL), and required libraries.
3. Create database: Create DB and user; set appropriate encoding (UTF-8) and permissions.
4. Install Tarifficator Pro: Upload installer or package, run installer as documented by vendor, point installer at DB and specify ports and admin credentials.
5. Configure web server & TLS: Set NGINX as reverse proxy, install TLS cert (Let’s Encrypt or provided cert).
6. Start services & enable on boot.

4. CDR ingestion configuration

• Choose ingestion method: Direct DB pull, SFTP/FTP of CDR files, REST API, or syslog.
• Map fields: Ensure timestamps, caller/callee numbers, duration, call direction, and call cost fields are correctly mapped.
• Time zones & formats: Normalize timestamps to UTC or your billing timezone.
• Data validation: Enable checks for duplicate CDRs and incomplete records.

5. Tariff and rating setup

• Define rate sheets: Create rate tables per destination, timebands, and customer class.
• Apply rounding rules: Set rounding (per-second, per-minute, or billing increment).
• Set discounts & surcharges: Configure promotional rates, volume discounts, taxes, and regulatory fees.
• Test rating engine: Run sample CDRs to verify expected billed amounts.

6. Rating rules, routing & rating exceptions

• Number normalization: Apply number plan rules (E.164 formatting, prefixes).
• Least-cost routing (if applicable): Integrate with route cost tables.
• Exception handling: Define rules for failed calls, zero-duration calls, and blocked numbers.

7. Billing, invoicing & payments

• Invoice templates: Configure layout, currency, logos, and line-item detail level.
• Billing cycles: Set monthly/weekly cycles, pro-rata and mid-cycle adjustments.
• Export formats: Enable CSV, PDF, XML, or direct integration with accounting systems.
• Payment integration: Connect to payment gateways or export receivables.

8. Reporting & monitoring

• Standard reports: Revenue by trunk/customer, traffic by destination, cost vs. revenue.
• Alerts: Configure thresholds for unusual traffic or rating errors.
• Dashboards: Set executive and operations dashboards for real-time KPIs.

9. Testing & validation

• Unit tests: Validate tariff calculations with known inputs.
• Integration tests: End-to-end CDR ingestion → rating → invoice generation.
• Load testing: Simulate peak CDR volumes to confirm performance and DB scaling.
• User acceptance: Have billing and operations teams verify invoices and reports.

10. Security & compliance

• Access control: Role-based admin accounts and strong passwords.
• Encryption: TLS in transit and encryption at rest for sensitive data.
• Audit logs: Enable logging of billing changes and admin actions.
• Regulatory: Ensure tax handling and data retention meet local laws.

11. Rollout & cutover

• Parallel run: Run Tarifficator Pro in parallel with existing billing for one cycle.
• Reconcile results: Compare invoices and address discrepancies.
• Go-live: Switch production ingestion to Tarifficator Pro and monitor first cycle closely.
• Rollback plan: Keep previous system ready for quick rollback for one billing cycle.

12. Maintenance & scaling

• DB maintenance: Indexing, partitioning, and archiving old CDRs.
• Autoscaling: Add compute or read replicas for high throughput.
• Upgrades: Stage upgrades in staging before production.
• Support: Establish vendor support SLA and escalation paths.

13. Quick troubleshooting checklist

• No CDRs: check PBX export, network, and ingestion logs.
• Incorrect amounts: verify rate tables, rounding, and timezone.
• Performance issues: check DB indices, I/O, and memory; enable query profiling.

If you want, I can produce:

• A sample rate table and test CDR set, or
• A deployment checklist formatted as a task-ready table.
