Astervis vs Asternic: A Complete Comparison for Asterisk Call Centers in 2026

If you run an Asterisk-based call center, you've likely encountered Asternic Call Center Stats — one of the oldest queue monitoring tools in the Asterisk ecosystem. It's been around since the mid-2000s and has served thousands of call centers well.

But the call center landscape has changed dramatically. Teams expect real-time data, modern interfaces, and instant setup — not legacy PHP dashboards that require manual queue_log parsing. That's exactly why we built Astervis.

In this comparison, we'll give you an honest, feature-by-feature breakdown of both tools so you can make the right choice for your team.

Quick Overview

Pricing: Subscription vs One-Time License

This is where the two products differ most fundamentally.

Asternic Pricing

Asternic uses a perpetual license model:

• —Lite: Free (GPL3) — limited reports, scheduled data only, Flash charts (deprecated)
• —PRO: $500 one-time — full features, real-time view, HTML5 charts, 1 server
• —Devel: $2,000 one-time — includes PHP source, up to 5 servers
• —Annual maintenance: $100/year (PRO) or $400/year (Devel) for updates and support
• —Plugins: $50 each (Callback Report, Area Code Report, Agent Ranking)
• —Professional services: $80-$100/hour

First-year cost for PRO: $500 (license) + potentially $50-$150 in plugins = $550-$650 Ongoing annual cost: $100/year for updates

Astervis Pricing

Astervis uses a monthly subscription:

• —Starter: $119/month (unlimited agents)
• —Professional: $449/month (unlimited agents)
• —Business: $1,199/month (unlimited agents)
• —Enterprise: custom pricing (unlimited agents)

All plans include every feature — no plugins, no add-ons, no hidden costs.

Which Is Cheaper?

For a small team (10 agents), Asternic PRO is cheaper in the long run: $500 upfront + $100/year vs $588/year with Astervis Starter. After year one, Asternic costs only $100/year while Astervis continues at $588/year.

However, the Asternic price doesn't include:

• —The time cost of manual installation and configuration (30-60 minutes minimum)
• —Ongoing server maintenance (PHP, MySQL, Apache/Nginx updates)
• —No CRM integrations (you'll build custom ones or go without)
• —No agent management features (scheduling, leaderboards)
• —Limited real-time capabilities compared to WebSocket-based streaming

For teams that value modern tooling, instant setup, CRM integrations, and continuous updates with new features, Astervis delivers significantly more value per dollar.

Feature Comparison

Real-Time Monitoring

Astervis advantage: True real-time via WebSocket streaming means data appears in under one second. Asternic PRO polls for changes periodically, which introduces noticeable delays during high-traffic periods. The Lite version only runs scheduled data imports — meaning you might be looking at data that's minutes or even hours old.

Reporting & Analytics

Where Asternic has an edge: The PRO version's Report Designer lets you create custom formulas and reports — something power users appreciate. Scheduled email reports are also a nice workflow feature.

Where Astervis leads: Trunk analytics (SIP monitoring) is a feature Asternic doesn't offer at all. Our interactive, modern charts are built with the latest visualization libraries, making data exploration faster and more intuitive.

Agent Management

Astervis advantage: Built-in agent leaderboards create healthy competition and boost productivity — Asternic charges $50 extra for a basic ranking plugin. Schedule management is entirely absent from Asternic, meaning you need a separate tool to manage agent shifts and schedules.

CRM & Integrations

Astervis advantage: Native CRM integrations connect your call data to your customer database. Bitrix24 and AmoCRM are the most widely used CRMs in the Asterisk ecosystem — particularly in Eastern Europe, Latin America, and Central Asia where Asterisk adoption is strongest. Asternic offers no CRM integrations whatsoever.

Setup & Technology

Critical note about Asternic Lite: The free version still uses Flash for charts. Flash was officially discontinued by Adobe in December 2020, and most modern browsers completely block it. This means Asternic Lite's charts literally don't work in any modern browser without workarounds.

The Technology Gap

Let's be direct about the fundamental technology difference.

Asternic was built in the mid-2000s with the tools available then: PHP server-side rendering, MySQL for storage, and queue_log file parsing for data ingestion. It works, it's proven, and for basic reporting needs, it gets the job done.

Astervis was built in 2024 with a modern stack designed for real-time analytics:

• —TimescaleDB — a time-series database purpose-built for analytics workloads, offering 10-100x faster aggregation queries compared to MySQL
• —Kafka/Debezium — event streaming for real-time change data capture
• —Redis — in-memory caching for sub-millisecond data access
• —WebSockets — push-based data delivery (no polling, no page refresh)
• —React/Next.js — responsive, interactive UI that works on any device
• —Docker — containerized deployment for consistency and easy updates

This isn't just a cosmetic difference. It means:

1. —Data freshness: Astervis shows data in real-time. Asternic parses queue_log files periodically.
2. —Query performance: TimescaleDB can aggregate millions of call records in milliseconds. MySQL struggles with large CDR tables.
3. —Scalability: Astervis handles hundreds of concurrent agents without performance degradation.
4. —Maintainability: Docker containers update with a single command. Asternic requires manual PHP/MySQL upgrades.

When to Choose Asternic

Be honest — Asternic is still a valid choice in some scenarios:

1. —

   Budget is the primary concern: If you need reporting and $500 one-time is your absolute maximum, Asternic PRO is cheaper long-term than any subscription service.

2. —

   You only need basic historical reports: If real-time monitoring isn't critical and you just need end-of-day/week reports, Asternic Lite (free) might be sufficient.

3. —

   You want custom report formulas: Asternic PRO's Report Designer allows creating custom calculated metrics — something Astervis doesn't offer yet.

4. —

   You're already running it successfully: If Asternic is working well for your team and you don't need CRM integrations or modern real-time features, there's no urgent reason to switch.

When to Choose Astervis

Astervis is the better choice when:

1. —

   Real-time monitoring matters: If supervisors need to see what's happening right now — not 30 seconds ago — Astervis's WebSocket-based streaming is essential.

2. —

   You use Bitrix24 or AmoCRM: Native CRM integration connects call data to customer records automatically.

3. —

   You want modern UX: Responsive design that works on phones, tablets, and desktops. Interactive charts you can explore, not static images.

4. —

   Setup speed is important: One command, 5 minutes, done. No PHP configuration, no MySQL schema setup, no Apache virtual hosts.

5. —

   You need agent management: Leaderboards, scheduling, and performance tracking go beyond basic reporting.

6. —

   You're scaling: TimescaleDB handles growing call volumes better than MySQL for analytics workloads.

7. —

   Your team expects modern tools: New hires familiar with tools like Datadog, Grafana, or Amplitude expect the same quality in their call center monitoring tool.

Migration: From Asternic to Astervis

Switching from Asternic to Astervis is straightforward because both tools read from the same source — your Asterisk instance:

1. —

   Install Astervis alongside your existing Asternic setup (they don't conflict):

   curl -fsSL https://api.astervis.io/api/releases/install.sh | bash
2. —

   Connect to Asterisk via AMI — Astervis reads live data, so there's no data migration needed.

3. —

   Run both in parallel for a week to validate data accuracy.

4. —

   Retire Asternic when you're confident in the switch.

The entire process takes 5 minutes for installation, and you can keep Asternic running during the transition period.

The Bottom Line

Asternic is a battle-tested PHP tool that's served the Asterisk community well for nearly two decades. If budget is your only concern and you don't need real-time data, CRM integrations, or modern UX, the $500 PRO license offers solid basic reporting.

Astervis represents the next generation of Asterisk call center analytics. It's built with modern technology that delivers real-time data, beautiful visualizations, CRM integrations, and agent management features that Asternic simply doesn't have — all installable in 5 minutes.

The question isn't whether Asternic works. It's whether a tool built in the PHP 5 era can meet the expectations of a 2026 call center team.
