Sito con registrazione clienti + ricarica credito collegato a centralino VoIP
Obiettivo
Cerco un tecnico freelance che realizzi da remoto un sistema semplice e funzionante per telelavoro, basato su software open source già esistente (ASTPP, A2Billing, FreePBX). Il sistema deve permettere ai clienti di:
Registrarsi e creare un account.
Ricaricare un credito prepagato (a scalare) tramite Stripe o PayPal.
Usare il credito per effettuare chiamate tramite centralino VoIP open source (FreePBX/Asterisk).
Visualizzare saldo, storico ricariche e chiamate (CDR).
Requisiti tecnici
Centralino VoIP: FreePBX/Asterisk con integrazione ASTPP o A2Billing per gestione credito.
Portale web utente: login, saldo, ricarica, storico chiamate, ricevute PDF.
Pagamenti online: Stripe/PayPal con webhook per aggiornamento saldo.
Sicurezza: HTTPS con Let’s Encrypt, accesso remoto (VPN), backup di base.
Installazione su mini PC fanless (Ubuntu/Debian).
Deliverable
Sistema funzionante installato e testato sul mio mini PC.
Documentazione di base per gestione utenti e tariffe.
Una breve sessione di formazione per l’uso.
Specificare esperienza con ASTPP / A2Billing / FreePBX.
Inviare un portfolio di lavori simili (centralino + billing).
Proposte solo con soluzioni open source già pronte, non sviluppo da zero.
