What ASTPP is

ASTPP is an open-source platform for telecom businesses that brings VoIP switching, call routing, and billing into one system. Its telephony functions combine Class 4 and Class 5 softswitch capabilities with an IP PBX and Session Border Controller. Billing covers real-time prepaid charging, postpaid invoices, reseller billing, and configurable billing cycles. Teams can manage customer accounts, plans, invoices, payment collection, usage ratings, and DIDs, including their purchase, assignment, configuration, billing, and release. Routing can be set by cost, priority, percentage, time, or quality. REST APIs cover account management, call detail records, rates, and DIDs; listed integrations include WHMCS, Zoho CRM, Salesforce, vtiger CRM, Stripe, and n8n. Security features include fraud detection, encrypted SIP and gateway credentials, and Google and Microsoft single sign-on. ASTPP is available through the web, an API, and self-hosted deployment.

ASTPP is a VoIP billing and management platform for telecom operators. It is strongest for businesses that need call handling, routing, customer billing, and DID management in one system. Its free Community Edition lowers the cost of entry, but the absence of security updates and support makes the edition choice a serious operational decision.

Overview

ASTPP combines Class 4 and Class 5 softswitch, IP PBX, and Session Border Controller capabilities with billing and telecom management. For an operator coordinating call traffic and customer accounts, that breadth can make one platform serve several core jobs. It also raises the importance of choosing an edition that fits the demands of a live telecom service: Community has limited or basic features and no security updates, while Enterprise adds advanced features, enterprise add-ons, unlimited support and upgrades, and no limit on data records.

The platform can be installed on a customer's server, and its maker describes cloud, on-premise, and high-availability deployments. REST APIs cover account management, call detail records, rates, and DIDs. Integrations include WHMCS, Zoho CRM, Salesforce, vtiger CRM, Stripe, and n8n, giving teams options for connecting telecom operations with business tools.

Key features

Call handling and routing

ASTPP supports least-cost, priority, percentage-based, time-based, and quality-based routing. That choice matters to operators with different traffic policies: they can direct calls according to cost or other criteria rather than relying on one routing approach. Combined with Class 4 and Class 5 softswitch functions, IP PBX, and Session Border Controller capabilities, it targets telecom operations with varied call flows. Teams should confirm that their chosen edition provides the features they need, since Community is limited or basic.

Billing and DID management

Billing covers real-time prepaid charging, postpaid invoicing, reseller billing, and configurable billing cycles. The platform also supports plan management, customer accounts, invoice generation, payment collection, and usage rating. This makes ASTPP a fit for providers serving customers through more than one billing model, including resellers. DID management spans purchase, assignment, configuration, billing, and release, so operators can handle number administration alongside call service and billing.

Integration and security

REST APIs expose account, call detail record, rate, and DID operations. The named integrations include CRM, payment, and workflow tools, which can help teams connect ASTPP with existing processes. Listed security capabilities include fraud detection, encrypted SIP and gateway credentials, and Google and Microsoft single sign-on. Those capabilities do not remove the central edition trade-off: Community receives no security updates, while Enterprise includes upgrades and support.

Enterprise EditionCustom pricing; contact salesAdvanced features, enterprise add-ons, unlimited support and upgrades, and no limit on data recordsRequires a sales conversation

Community Edition suits individuals and businesses seeking a free version, particularly where limited features and the lack of support and security updates are acceptable. It removes the license charge, but those omissions make it a difficult fit for operators who need dependable production support or security maintenance. Enterprise is intended for small to large enterprises; its support, upgrades, and unrestricted data records make it the more complete option for ongoing operations, with cost determined through sales.

Platforms

ASTPP supports API access, self-hosted deployment, and web use. The maker describes cloud, on-premise, and high-availability deployments, offering deployment choices for operators with different infrastructure arrangements. Its self-hosted option is most relevant to teams prepared to install and manage a system on their own server.

Who it's for

ASTPP is a strong candidate for telecom businesses that need switching, routing, prepaid or postpaid billing, reseller billing, and DID administration together. Its API and integrations also suit teams that need to connect those operations with customer, payment, or workflow tools. Community can serve individuals and businesses looking for a free starting point, while operators that depend on support, upgrades, security updates, or unlimited data records should assess Enterprise.

It is less suitable for a team that needs security updates and vendor support while staying on a free edition. Self-hosting also means the platform is better matched to operators able to manage their own deployment than to buyers seeking a service with no infrastructure responsibility.

Pros and cons

  • Broad telecom scope: Softswitch, IP PBX, Session Border Controller, routing, billing, and DID management are brought into one platform.
  • Flexible billing and routing: Prepaid, postpaid, reseller billing, configurable cycles, and five routing criteria support varied telecom operations.
  • Free entry point: Community Edition is free forever, giving individuals and businesses a way to start without a license fee.
  • Community's operational gaps: Limited features, no support, and no security updates constrain its suitability for production use.
  • Enterprise price requires sales contact: Support, upgrades, and unlimited data records come with custom pricing rather than a published amount.
  • Deployment responsibility: The self-hosted option requires the customer to install the system on its server.

Verdict

ASTPP is best for telecom operators who want switching, routing, billing, and DID management in one platform and can manage its deployment. Its breadth, APIs, integrations, and free Community Edition make it a compelling place to start. The deciding drawback is the free edition's lack of security updates and support; organizations that need those protections and ongoing help should compare Enterprise's custom pricing with their requirements before committing.

Verdict

Choose ASTPP if your telecom business needs switching, routing, billing, and DID management in one platform, with a free Community Edition to start. Look elsewhere if you require support or security updates on the free edition; Enterprise Edition includes support and upgrades, with pricing available through sales.
