Methodology
Every product is scored out of 10 using the same seven criteria and weights. We only use information the vendor publishes (pricing pages, documentation, help centers) or that appears on independent review sites, and we link to the source of each fact. When a vendor does not publish something, we mark it as 'Not stated' and it earns no points.
Criteria and weights
| Ease of setup | 15% | Self-service in minutes scores highest; sales-led projects, setup fees and multi-week implementations score lower. |
|---|---|---|
| Pricing & value | 20% | Real cost of getting started (price × minimum licences; up to €60/month = full marks) and value: the lowest cost per included minute (€0.15 or less = full marks; per-call plans assume a 3-minute average call). 'Contact sales only' scores lowest. |
| Free trial | 10% | A free trial or free plan you can start without talking to sales. |
| Languages | 15% | Number of call languages (35+ = full marks), Polish support and automatic language switching. |
| Features | 25% | Booking with calendar sync, call transfer, SMS, recordings, transcripts, website-trained knowledge, API, webhooks, custom voice, CRM integrations. |
| Europe & GDPR | 10% | GDPR / EU data processing, EU-based company and phone numbers in Poland or the EU. |
| Third-party reviews | 5% | Average rating and number of reviews on G2, Capterra or Trustpilot for the AI product itself (company-wide ratings of phone-system vendors are not counted). |
Where the data comes from
Prices, plans, languages and features are collected from each vendor's website and documentation. Prices are shown in the vendor's currency; for scoring we convert them to euros at fixed approximate rates. Data was last checked on November 7, 2026.
Editor's choice and disclosure
Editor's choice labels mark the products we recommend for most small and mid-sized businesses. Telofia and Voxiora are made by a company affiliated with the publisher (see About) and are marked 'Publisher's partner'. Their scores are calculated with exactly the same formula as every other product.
