## The panel's verdict

fonial, a Cologne cloud-telephony vendor (fonial GmbH, HRB 83052, an EnBW subsidiary) selling a cloud PBX and SIP trunking, scores highest on pricing transparency — a flat 8 — and sovereignty at 7-8. Prices are public line by line: 3,90 € net per activated number per month, 0,00 € set-up, free porting, monthly cancellation, plus a downloadable price list and calculator. The German chain is documented — Plusnet's three geo-redundant German data centres, named subprocessors in Germany, Slovenia and Luxembourg — though the ISO 27001 is the hoster's, Google appears with a Privacy Shield certification cited as the safeguard, and where the AI partner ScaleTalk processes calls is not stated. Calling and routing lands at 5-6 (numbers from all 5,200 German local networks, queues with skill-based routing in the PLUS tariff), and network and compliance at 5-6. Weakest are apps and devices, contact centre and integration and admin, each 4-5, where we found no public information on desk-phone provisioning, agent states, wallboards, CRM pop-ups, single sign-on, SLA credits or emergency calling. Score spreads never exceed one point.

**Speaks for it:**
- Pricing is public line by line — 3,90 € net per activated number per month, 0,00 € set-up, free porting, monthly cancellation — with a downloadable total price list, a calculator and a worked example.
- The sovereignty chain is documented: fonial GmbH of Cologne as an EnBW subsidiary, hosting in Plusnet's three German data centres, named subprocessors, and a data-processing agreement with TOMs downloadable in the customer account.
- Numbers from all 5,200 German local networks with free porting, an IVR with up to ten actions, and unlimited queues with skill-based routing included in the PLUS tariff.
- Microsoft Teams can serve as the full phone system with an automated setup, at 9,90 € per account.
- A public status page, the Bundesnetzagentur named as supervisory authority, and carriers Deutsche Telekom, Vodafone and Telefonica named.

**Held against it:**
- We found no public information on call recording, on emergency calls with a registered caller location, or on how long a porting takes.
- The named phone makers snom, Gigaset, Yealink and Mitel appear on the site only as image credits, and we found no public device prices.
- We found no public information on agent states, wallboards, live monitoring or statistics per agent and queue — the documented dashboard shows a cost overview and an event monitor.
- The HTTP/JSON API must first be unlocked by support and covers click-to-dial and call records rather than full administration, and we found no public information on single sign-on or two-factor authentication.
- The ISO 27001 and ISO 9001 certificates belong to hosting partner Plusnet, the only availability statement is the 100 % Ausfallsicherheit marketing claim, and we found no published SLA credits.

**Best for:**
- You need a German cloud phone system for a small office or multi-site team and want to compute the full monthly cost from public prices.
- Your procurement requires a German contracting entity with named hosting and subprocessors, and you can accept that the voice AI runs on a certified partner platform.
- Your team already uses Microsoft 365 and wants Teams as the phone client at 9,90 € per account.
- You need SIP trunking alongside the PBX — number blocks, 1 to 200 channels, compatibility with PBX systems such as 3CX.

**Avoid if:**
- You run a supervised hotline or contact centre and need wallboards, agent states or per-agent statistics — the documented dashboard is a cost overview and an event monitor.
- You depend on auto-provisioned desk phones or a DECT fleet — the named makers snom, Gigaset, Yealink and Mitel appear on the site only as image credits.
- You need CRM caller pop-ups, automatic call logging or single sign-on on day one — the documented API must be unlocked by support and covers click-to-dial and call records.
- You need an availability commitment with credits in writing before signing — ask the vendor: the public pages we read do not show it

## Scores by judge and criterion

Scores out of 5, each judge scoring independently against the published rubric (v1). "n/r" = not rated: the vendor publishes no price, or the judge found no public information on that criterion.

### The judges

- **The Office Manager** (v1.0): Runs the office of a tax advisory firm with twenty-five staff in Hanover, where the old phone box in the server cupboard is being switched off by the carrier. The firm's number has been on every letterhead for thirty years and must not change. Wants the number ported without a gap, a greeting and a queue during the tax deadline weeks, voicemail by email, the desk phones kept, and a monthly bill the partners can read without calling anyone.
- **The IT Administrator** (v1.0): IT administrator at a machine builder with 280 staff on three sites in Baden-Württemberg, with production halls on DECT handsets, the office on Microsoft Teams and a service team abroad. Wants desk and DECT phones provisioned without touching each one, Teams calling with the company numbers, users created from Entra ID with single sign-on, an API for the number plan, and an emergency call from a home office that reaches the right control centre.
- **The Contact Centre Lead** (v1.0): Leads customer support for an online shop for bicycle parts, with eighteen agents in Leipzig and a hotline in German and English. On Mondays after a sale the queue reaches forty callers. Wants skills-based queues, a wallboard, callbacks instead of hold music, listen and whisper for training new agents, reports per agent and hour, and call summaries in the helpdesk without anyone typing them.
- **The Inside Sales Lead** (v1.0): Leads twelve inside sales reps at a B2B software company in Munich who call prospects in Germany, Austria and Switzerland from HubSpot. Wants click-to-call and a power dialer in the CRM, every call and its recording logged on the contact, local numbers in each country, the mobile app showing the company number at trade fairs, and AI notes that a rep can trust before the follow-up email.
- **The Data Protection Officer** (v1.0): External data protection officer for a group of six medical practices whose patients call about appointments, results and prescriptions. Knows that call records fall under the secrecy of telecommunications and that a recorded or transcribed call can hold health data. Reads the subprocessor list, asks which AI model writes the transcripts and where, wants encryption on by default, and needs a DPA and a retention period before any call is recorded.
- **The Skeptic** (v1.0): Has seen "all calls included" that excluded mobile numbers abroad, a "five-minute setup" followed by six weeks of porting, and an "AI assistant" that sent every recorded call to a model in the US. Asks what porting the numbers back out costs and how long it takes, whether the desk phones still work after leaving, who carries the calls, what the SLA pays when the platform is down — and what the second year costs.
