As of 6 Nov 2026, the panel rates Aircall 3/5 and RingCentral RingEX 3/5 in Cloud Telephony (VoIP & Cloud PBX). Weighted by what each judge cares about, 1 of the 6 judges picks Aircall and 5 pick RingCentral RingEX. Aircall scores higher on 1 of 6 criteria (European sovereignty). RingCentral RingEX scores higher on 5 of 6 criteria (Apps, desk phones & Microsoft Teams, Calling, numbers & call routing, Reliability, call security & telecoms compliance, plus 2 more). Provenance — Aircall: EU-Made; RingCentral RingEX: Rest of world. Ratings are the AI panel’s opinion, formed from public evidence: how scores are made.
RingCentral RingEX takes the technical rows: six judges lean its way on calling and routing (7.0 to 5.8), apps and devices (5.8 to 4.2) and network and compliance (7.0 to 6.0), with integration and administration close (7.0 to 6.8; one lean, five ties); the contact centre splits the bench, 3 leans to RingEX and 3 ties (8.0 to 7.5). Aircall takes sovereignty 6.5 to 3.8, six judges leaning its way; its verdict credits a published processing agreement, CNIL supervision and per-country subprocessor list and weighs a US voice and transcription chain, and RingEX's privacy notice states EEA and UK data may be transferred to and stored on servers in the United States and Switzerland. Pricing transparency: Aircall 5.7 to 4.3, five leans, one tie; RingCentral publishes no prices. Five judges' totals favour RingEX, IT administrators 6.5 to 5.4; the data-protection officer takes Aircall, 6.4 to 6.2. No overall winner emerges.
Choose Aircall if
You need a published processing agreement, CNIL supervision and a per-country subprocessor list on file — the credits behind Aircall's sovereignty lean, 6.5 to 3.8 with six judges leaning its way.
Your compliance policy rules out a privacy notice stating that EEA and UK data may be transferred to and stored on servers in the United States and Switzerland — the finding beneath RingEX's sovereignty mean of 3.8.
You need licence prices in the open for budget sign-off — Aircall publishes licence prices and takes pricing transparency 5.7 to 4.3 (five leans, one tie); number and porting prices are not public.
You are buying under a data-protection mandate — the data-protection officer is the judge whose weighted total favours Aircall, 6.4 to 6.2.
Choose RingCentral RingEX if

The Inside Sales Lead
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.

Criterion by criterion
Calling, numbers & call routing
Aircall
Local, toll-free and mobile numbers in over 100 countries with porting of existing numbers handled by the vendor, IVR, queues, ring groups by location, language or skill, time-based routing, voicemail, three-digit extensions and recording with pause-resume give my DACH team the routing core. I found no public information on emergency calls with the caller's location, fax, number blocks, busy lamp fields, or the porting process with its timelines, so it stays below the top band.
RingCentral RingEX
The drag-and-drop IVR builder, queues with one-by-one, group or simultaneous answer orders, separate business-hours, after-hours and holiday greetings, warm transfer, configurable outbound caller ID and voicemail-to-email transcription cover what my reps need at the desk, and free number porting with a stated seven-to-fourteen business day window is exactly what I ask a provider before moving twelve lines. Emergency calling for Germany is described down to the local-area-code rule and transmission of the registered location with a callback number, and numbers are offered across more than 75 countries. We found no public information on number blocks, call park or busy lamp fields, which keeps me off the top rung.
Apps, desk phones & Microsoft Teams
Aircall
iOS and Android apps that carry business calls without exposing the private number, access via browser or app on laptops and tablets, and a Microsoft Teams integration with presence sync and outbound calling from the contact tab are all documented — the trade-fair scenario works on paper. I found no public information on desk phones from named makers with automatic provisioning, devices for sale or rent, or fixed-mobile convergence, which holds this mid-band.
RingCentral RingEX
Desktop, mobile and browser apps with presence sync and device switching are documented, outbound caller ID can be configured across every team member's device so the company number shows on mobile calls, and the Microsoft Teams story is deep — Embedded App and Direct Routing modes plus a Microsoft-certified contact centre with a heads-up display. The only provisioning documentation captured is a manual Yealink setup through the phone's web UI, and we found no public information on a supported desk and DECT phone list with automatic provisioning, device prices, or fixed-mobile convergence with a SIM.
Call centre, analytics & AI
Aircall
This is the closest fit for my floor: click-to-dial and the Power Dialer, queue callback, ring groups by skill, call whispering with live monitoring, Analytics and Analytics+ dashboards with live and historical data, AI transcription and summaries, an AI receptionist in 38 languages, and WhatsApp and SMS beside calls. I found no public information on listen and barge or on workforce management and quality scoring, which the top band would require.
RingCentral RingEX
Preview, progressive, predictive and voice-broadcast dialers are exactly the power dialer my team would run all morning, and supervision with listen, whisper and barge plus skills, priority and talk-time routing sits alongside 250+ prebuilt reports, real-time dashboards and AI quality scoring across 100 percent of interactions. Real-time AI notes with action items, AVA transcription of every conversation, sentiment and root-cause analysis and an AI Receptionist sold standalone or as an add-on, with SMS and messaging beside calls, would let a rep trust the summary before the follow-up email. We found no public information on callbacks offered in queue or the languages the transcription supports, which is what I would probe in a demo.
CRM integration, API & administration
Aircall
HubSpot with CTI pop-ups, plus Salesforce, Zendesk and Pipedrive among 250+ native integrations, with click-to-dial and automatic logging of calls, recordings, comments and tags into the CRM record; a documented REST API and webhooks across calls, contacts, users, numbers and analytics; SAML single sign-on, SCIM on the Enterprise plan, user roles and two-factor authentication. I found no public information on audit logs, bulk user import, SIP trunks for an existing PBX, or partner accounts with sub-customers.
RingCentral RingEX
Click-to-call with automatic call logging, screen pop-ups and customer context is documented for Salesforce, Zoho, Zendesk and Microsoft Dynamics, and the developer platform — 500+ APIs, SDKs in eleven languages, documented SCIM endpoints, an embeddable widget — plus audit trail, enforced multi-factor authentication, single sign-on, custom roles, multi-site management and bulk user adds covers how I would actually run it. We found no public information naming HubSpot specifically, which matters to my team, and none on partner or reseller accounts or SIP trunks documented for named PBX systems; bring-your-own-carrier appears only as a coverage option.
Reliability, call security & telecoms compliance
Aircall
A public status page with per-component 90-day uptime, a stated availability of 99,95 %, TLS/SRTP and AES-256 documented, SOC 2 Type 2 with committed annual third-party audits, penetration tests and a bug bounty, Twilio named as the carrier behind the voice, and recording retention rules in the data processing agreement. I found no public information on an SLA with credits, toll fraud protection, emergency calling from softphones and home offices, or registration with a national telecoms regulator — and for a Munich sales floor the emergency-calling silence is the gap I notice most.
RingCentral RingEX
A published 99.999 percent availability claim backed by a stated 19-quarter record of under 79 seconds of downtime, ISO 27001, 27017, 27018 and 22301 plus SOC 2 and SOC 3 certificates, C5 attestation reports in English and German for both RingEX and RingCX, and annual independent audits provided on request under NDA would get through our security review. TLS and SRTP are documented, and the emergency calling policy reads like an operator's document with per-country routing rules including Germany, registered-address obligations and home-office limitations spelled out. We found no public information on registration with the Bundesnetzagentur, an SLA with credits, a public incident history or toll-fraud spending limits, so I stop short of the top.
European sovereignty
Aircall
The contracting entity is Aircall SAS in Paris, a data processing agreement is published with the CNIL as supervisory authority, and the subprocessor list is public with each provider's country — that part is done properly. The AI pages state that transcripts and recordings are stored in the EU from day one on AWS, while the same subprocessor list shows transcription from call recordings performed by AssemblyAI and Deepgram in the USA and voice carried by Twilio in the USA under standard contractual clauses. The privacy policy names the United States, Europe, Australia and India as storage locations, so the chain is documented and partly European but short of sovereign end to end.
RingCentral RingEX
German customers contract with RingCentral Germany GmbH in Hamburg under German law with the District Court Munich I named for disputes, a data processing agreement with EU Standard Contractual Clauses is published, a subprocessor list exists and the data protection officer sits in Dublin. The privacy notice states that information collected in the EEA and the UK can be transferred to and stored on servers in the United States and Switzerland, and we found no public information on EU hosting for recordings, transcripts and account data or on where the listed subprocessors sit.
Pricing transparency
Aircall
Plans are public with per-user prices and inclusions — Essentials at 30 € pro Lizenz/Monat with 1.000 Min. outbound national and SMS/MMS, Professional at 50 € pro Lizenz/Monat with unlimited domestic outbound and the Power Dialer, a 25 % annual saving, three-licence minimum — and add-ons are unusually well priced (AI Assist Pro 49 € pro Lizenz/Monat, Analytics+ 15 € pro Lizenz/Monat, WhatsApp 10 € pro Lizenz/Monat, voice-agent packages from 210 €/Monat). I found no public prices for numbers, porting and devices, no per-minute list for calls beyond the included minutes, and no stated set-up fees or VAT treatment, so I cannot compute the full annual cost for my twelve reps from public pages alone.
RingCentral RingEX
The only price figure captured is a starting price of 65 $ per user per month with unlimited minutes on the contact centre page, while the German pricing page lists plan inclusions — 100, 500, 1,000 and 2,000 minutes per user — in euros for Germany with a compare-all-features view, and porting is documented as free. A Germany outbound call rates document exists in the legal library, prices are stated exclusive of taxes, payment is due in thirty days and non-renewal notice is thirty days, but we found no public information on the per-plan euro prices, number costs, vanity-number fees, add-on prices for the AI Receptionist or AI analytics, device prices or set-up fees.
