ASTPP review
A broad, free-core billing platform for VoIP providers willing to manage feature limits.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
ASTPP is an open-source VoIP billing and telecom operations platform for wholesale carriers, ITSPs, retail VoIP providers, and SIP trunking businesses. It brings real-time usage rating and charging, prepaid and postpaid billing, Call Detail Record processing, tariff and rate management, customer and reseller accounts, multi-tenancy, invoicing, payment collection, routing, DID management, reporting, and alerts into one system. Cloud and on-premises deployment options are available, making it relevant to providers that need control over billing operations and account structures.
The Community Edition is free forever and includes access to community add-ons, but its feature set is limited. The published plan structure lists the Enterprise Edition with all Community Edition features plus advanced features, enterprise add-ons, unlimited support, unlimited upgrades, and no limit on data records. Enterprise pricing is handled through sales. The main trade-off is clear: the free edition lowers the entry barrier, while providers that need broader capabilities, ongoing support, security updates, or fewer data constraints should consider Enterprise. The Community Edition has no support or security updates, which is a significant consideration for production telecom operations.
ASTPP’s ecosystem covers telecom infrastructure, business systems, and payment services. Integrations include FreeSWITCH and OpenSIPS, along with WHMCS, Zoho, Salesforce, Stripe, PayFast, and PayPal. That combination supports connections across switching, customer management, billing workflows, and payment collection. Providers choosing ASTPP should be comfortable evaluating the limited Community Edition against their operational requirements and managing the platform within their preferred deployment model. It suits budget-conscious VoIP and telecom providers that value open-source control and broad billing coverage; organizations needing fully supported operations from the outset should look at the Enterprise Edition instead.
