## The panel's verdict

Calling and routing scores 7 across the bench: multi-level auto receptionists, call queues with distribution and overflow rules, number porting, recording with transcription, and emergency-calling pages covering registered locations and nomadic detection. Network and compliance scores 6-7, backed by an ISO 27001:2022 certificate issued 17 February 2026 naming Zoom Phone in scope, BSI C5, SOC 2 Type 2, a 99.999% uptime SLA with Zoom Node local survivability, and SIP over TLS 1.2 with AES 256-bit encryption. The contact center scores split 6-7 — judges crediting included AI call summaries, live transcription and the €23 AI receptionist score above those citing missing callback, dialer and reporting evidence. Sovereignty is the weakness, scored 1-3: the contracting entity is Zoom Communications, Inc. of San Jose, California, with an EU representative in Cork; hosting is stated only as remote data centres; subprocessors appear as unnamed categories; and we found no public information on data residency, a data processing agreement, or where recordings are stored. Pricing transparency scores 5-7: euro per-user prices and add-ons are public, though the pages give different figures for Business Plus.

**Speaks for it:**
- Calling and routing scored 7 across the bench on porting, multi-level auto receptionists and queues with automatic distribution and overflow rules
- An ISO 27001:2022 certificate issued 17 February 2026 names Zoom Phone in its scope, independently audited, with BSI C5 and SOC 2 Type 2 also listed
- A 99.999% uptime SLA is paired with local survivability through Zoom Node devices for internet or cloud outages
- Microsoft Teams is covered three ways — an embedded Zoom app at no additional cost, a Direct Routing add-on and Operator Connect with no SBC to maintain
- Per-user euro prices are public, including Global Select Metered at €15.18 per user per month billed annually excluding VAT, with add-ons itemised from €4.65 per month

**Held against it:**
- Sovereignty is the weakest criterion, scored 1 to 3, with a US contracting entity and no stated hosting country
- Subprocessors are described only as vendor categories for infrastructure, support and payments, with no named list of locations
- We found no public information on a published data processing agreement, on data residency, or on where call recordings and AI transcripts are hosted
- The captured pages give different figures for the Business Plus plan, 22,54 € and €26.68 per user per month
- We found no public information on porting costs, device prices, set-up fees or international per-minute rates, and pricing above 50 licenses is on request

**Best for:**
- You are migrating a PBX to the cloud and need inbound call handling — auto receptionists, queues with overflow rules and number porting — where calling and routing scored 7 across the bench
- Your procurement audits certifications before signing — an ISO 27001:2022 certificate naming Zoom Phone in scope, plus BSI C5 and SOC 2 Type 2, is published
- Your organisation standardises on Microsoft Teams — embedded Zoom calling at no additional cost, Direct Routing and Operator Connect are all documented
- You run Avaya or Mitel today and want a staged move — hybrid deployment with those named systems is documented

**Avoid if:**
- Your compliance review requires EU data residency or a published data processing agreement — the contracting entity is Zoom Communications, Inc. of San Jose, California, and hosting is stated only as remote data centres
- You must budget the full first year before committing — plans are billed annually as a single upfront charge, and we found no public information on porting, device or set-up costs
- You need more than 50 licenses at a published price — pricing above 50 licenses is on request

## 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.
