Instead of ASTPP
ASTPP alternatives
ASTPP serves telecom businesses that need open-source VoIP billing and management with call-control components. It combines Class 4 and Class 5 softswitch, IP PBX, Session Border Controller, prepaid and postpaid billing, reseller accounts, configurable cycles, routing choices, DID management, REST APIs, integrations, fraud detection, single sign-on, and self-hosted or cloud deployment. Its Community Edition is free, while Enterprise adds advanced features, support, and upgrades. However, the free edition has limited or basic features, no support, and no security updates; Enterprise pricing requires contacting sales. Its platform coverage centers on API, self-hosted, and web access.

Alternatives make sense when you need ISP subscriber operations, network monitoring, provisioning, broader customer self-service, or billing for industries beyond VoIP. Some options add mobile apps, branded portals, tickets, optical-network management, taxation, collections, or multichannel service workflows. Compare those functions with your own operation, then weigh deployment, integrations, platform access, support, and pricing. Free plans and trials can reduce initial cost, while several enterprise systems require a quote.
