3. Telgoo5 – Best SaaS option for MVNOs

Telgoo5 is the most accessible SaaS platform for wholesale VoIP operators and MVNOs seeking to avoid on-premise infrastructure.

Why it ranks third:

Telgoo5 targets the MVNE/MVNO segment, providing subscription-based billing without upfront hardware costs. As a cloud-native platform, it offers automatic updates and vendor-managed infrastructure, reducing operational overhead for smaller operators. However, it offers less customisation than carrier-grade platforms like JeraSoft.

Key features:

• SaaS-based, no on-premise infrastructure required
• MVNE/MVNO-focused workflows
• Recurring billing for bundled services
• Automatic updates and cloud scalability
• Subscription pricing model (typically £2,000-5,000/month)

Best for: MVNOs, smaller wholesale operators, operators prioritising operational simplicity over deep customisation

Limitation: Telgoo5 is less suited for high-volume wholesale interconnect scenarios that require complex LCR and settlement logic.

Market perception: Accessible and modern, but less powerful than carrier-grade alternatives.

 

4. ASTPP – Best open-source option for technical teams

ASTPP is a leading open-source VoIP billing platform, favored by startups and operators with strong internal development teams.

Why it ranks fourth:

ASTPP is free to download and deploy, offering the lowest-cost entry point for wholesale VoIP billing. Operators with technical expertise can use it as a flexible environment for testing billing logic and integrating custom features. However, support is limited to community forums and paid third-party consultants, with no vendor SLA. Most operators migrate to commercial solutions like JeraSoft as they scale beyond 5,000 to 10,000 subscribers or require guaranteed uptime.

Key features:

• Open-source, zero licensing cost
• Flexible, customisable codebase
• Community-driven development
• Suitable for experimental deployments
• Requires significant in-house technical expertise

Best for: Startups, small VoIP operators with strong technical teams, operators testing billing logic before commercial deployment

Limitation: ASTPP does not offer a professional SLA. Support is community-based, security updates are inconsistent, and scalability requires custom optimisation.

Why it ranks fifth:

AlarisLabs specializes in real-time anomaly detection, SIM-box fraud identification, and traffic pumping alerts. Operators typically deploy AlarisLabs alongside existing billing systems such as JeraSoft or PortaOne to enhance fraud and revenue assurance. For wholesale carriers managing high-risk traffic, it is a critical complement to core billing platforms.

Key features:

• Real-time traffic anomaly detection
• SIM-box and traffic pumping alerts
• Revenue assurance analytics
• Integration with existing billing systems
• Enterprise-grade fraud management

Best for: Wholesale carriers prioritising fraud detection, operators handling high-risk traffic routes, and carriers requiring revenue assurance

Limitation: AlarisLabs is not a billing backbone and is designed to complement, not replace, a core billing system.

Market perception: Recognized as a leader in fraud and analytics, serving as a billing companion rather than a core billing solution.

 

What to look for in wholesale VoIP billing software

Selecting a wholesale VoIP billing platform requires a clear understanding of the technical and operational demands of carrier-grade networks. The following five features are essential for every wholesale operator:

Real-time CDR rating

Wholesale VoIP generates millions of call detail records per second. Your billing system must rate these in real time, not batch process them hours later. Real-time rating prevents credit overruns, enables dynamic pricing, and ensures accurate settlement with interconnect partners. Platforms like JeraSoft process 1M+ CDRs/second; platforms like ASTPP require custom optimisation to achieve this.

Dynamic least-cost routing (LCR)

Margin in wholesale VoIP is made or lost on routing decisions. Your billing system must integrate with your routing engine to apply the cheapest available route per call, then rate it correctly. This requires tight coupling between the switch and the billing platform. JeraSoft and PortaOne both handle this natively; ASTPP requires custom integration.

Interconnect settlement

Wholesale operators manage agreements with multiple carriers, each with different rates, settlement terms, and currencies. Your billing system must track these relationships, apply per-partner rates, and generate settlement reports for accounting. This is where carrier-grade platforms like JeraSoft excel and where SaaS platforms like Telgoo5 struggle.

Fraud detection

A single weekend of SIM-box fraud or traffic pumping can cost more than an annual software license. Modern wholesale billing platforms must include anomaly detection for unusual traffic patterns, spike alerts, and integration with fraud management tools like AlarisLabs. This is non-negotiable for operators handling international traffic.

Scalability and uptime SLAs

Wholesale carriers cannot afford downtime. Your billing system must scale horizontally to handle traffic spikes without degradation and include professional support with guaranteed response times. Open-source solutions like ASTPP offer no SLA; commercial platforms like JeraSoft include 24/7 support with defined uptime guarantees (typically 99.9%).

 

Wholesale vs retail VoIP billing – key differences

Wholesale and retail VoIP billing serve different business models and require different technical approaches:

Aspect	Wholesale	Retail
Volume	High (millions of CDRs/day)	Lower (thousands/day)
Pricing	Dynamic, per-route, per-partner	Fixed, per-plan
Settlement	Multi-party, currency-aware	Single party, single currency
Fraud risk	High (SIM-box, traffic pumping)	Lower (individual subscriber fraud)
Rating complexity	Complex (LCR, interconnect)	Simple (plan-based)
Support requirement	24/7 SLA critical	Standard business hours acceptable
Platform choice	JeraSoft, PortaOne, ASTPP	Telgoo5, Rev.io, Splynx

Wholesale operators require platforms built for complexity and scale. Retail operators can use simpler, SaaS-based solutions. Choosing a retail platform for wholesale use is a common mistake that leads to billing errors and lost revenue.
