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

Read this comparison as one judge. Each weighs the same scores by what they care about.
The Contact Centre Lead
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.

Criterion by criterion
Calling, numbers & call routing
Aircall
Numbers in over 100 countries, porting of existing numbers handled by their team, IVR, queues, ring groups grouped by location, language or skill, time-based routing with per-number business hours, voicemail, extensions, parallel calls and recording with pause are all documented — that covers the routing basics my Monday peaks need. We found no public information on emergency calls with a registered location, number blocks, call park and busy lamp fields or fax, and the porting timelines are not described, which keeps this in the middle of the range.
RingCentral RingEX
Drag-and-drop IVR menus, queues with ring groups, business-hours, after-hours and holiday answering rules, voicemail-to-email transcription, fax on a single number and free number porting typically within 7 to 14 business days are all documented, and emergency calling with a registered address is described in detail, including the German rule that the address must lie within the local area code. Numbers across over 75 countries and a visual call-flow editor bring it close to the top band. We found no public information on number blocks or call park and busy lamp fields, which keeps me a notch below.
Apps, desk phones & Microsoft Teams
Aircall
Access via web browser or app, iOS and Android apps, business calls from the mobile without exposing the private number, GSM fallback when the network degrades, and a Microsoft Teams integration with presence sync, contact search and outbound calls from Teams are documented. We found no public information on desk phones from named makers with automatic provisioning, DECT handsets, devices for sale or rent, or Teams calling via Direct Routing or Operator Connect with certification — hardware is only described generically as VoIP hardphones.
RingCentral RingEX
Desktop, mobile and browser clients with presence sync, device switching, and telephony inside Microsoft Teams through Direct Routing and an embedded app, with Microsoft certification named for the contact centre, cover what my agents touch daily. Yealink desk phones are documented, though the captured guide walks through manual provisioning from the phone's web interface, and hardware sales terms indicate devices are sold. We found no public information on fixed-mobile convergence, headset support or app store ratings.
Call centre, analytics & AI
Aircall
This is the strongest area for us: skills-based ring groups, callback out of the queue, call whispering with live monitoring, a power dialer, live and historical dashboards, an agent performance view with resolution and transfer rates, AI call summaries automatically logged into CRM or helpdesk, an AI receptionist in 38 languages, and SMS and WhatsApp beside calls — my whole training-and-queue wishlist is in print. We found no public information on listen and barge alongside the whisper function, on scheduled or exportable reports, or on sentiment analysis by name, so it sits just below the top.
RingCentral RingEX
This is close to what I run my Monday queue on: nine routing methods including skills-based and priority routing, discreet listen, whisper and barge-in for coaching new agents, four outbound dialers, over 200 prebuilt reports with real-time dashboards and alerting when queue limits are crossed, and AI transcription, summaries and sentiment with automatic after-call documentation into the CRM. An AI receptionist speaking multiple languages with mid-call switching, plus over twenty digital channels beside voice, is exactly the direction we want. We found no public information on callbacks offered while waiting in queue, and scheduled or exportable reports are not described — precisely the gap that hurts when forty callers are holding.
CRM integration, API & administration
Aircall
Over 250 native integrations including HubSpot, Salesforce, Zendesk, Pipedrive and Help Scout, CTI screen pops, automatic logging of calls, recordings, comments and tags into CRM or helpdesk, a REST API with webhooks across calls, contacts, users and numbers, SAML single sign-on, SCIM at Enterprise, user roles and two-factor authentication cover the caller pop-ups and untyped summaries my agents need. We found no public information on audit logs, bulk user import, SIP trunks for an existing PBX, or reseller accounts with sub-customers.
RingCentral RingEX
Click-to-call, screen pop-ups and automatic call logging are documented for Salesforce and Zoho, SCIM user provisioning is documented endpoint by endpoint, and administration shows custom roles, single sign-on with enforced multi-factor authentication, an audit trail, multi-site management and bulk user creation. With over 500 APIs and SDKs in eleven languages, the platform side is broad. We found no public information on webhooks, on SAML as the single sign-on protocol, or on partner and reseller accounts, and SIP trunks for a named PBX are not described.
Reliability, call security & telecoms compliance
Aircall
A public status page with 90-day component uptime and incident communication, a stated uptime of 99.95%, TLS and SRTP encryption of calls, AES-256 at rest, a SOC 2 Type 2 attested security programme with annual audits committed in the data processing agreement, regular penetration tests and retention rules per pricing plan give me reasonable confidence. We found no public information on emergency calls from home offices, registration with the German telecoms regulator, toll fraud spending limits, or SLA credits beyond the Enterprise-level SLA mention.
RingCentral RingEX
A 99.999 percent availability claim backed by a stated nineteen-quarter record of under 79 seconds of downtime, TLS and SRTP secure voice, encryption at rest, end-to-end encrypted calls in closed beta, and a remarkable certification set — ISO 27001, 27017, 27018 and 22301, SOC 2 and SOC 3, a C5 attestation in English and German, HITRUST, Cyber Essentials Plus and PCI — give me audit confidence. Emergency calling from softphones and home offices is documented in unusual detail, including handoff to the smartphone's native dialer. We found no public information on an SLA with credits, a public incident history, registration with the Bundesnetzagentur, or toll-fraud protection.
European sovereignty
Aircall
The contracting entity is Aircall SAS in Paris, a data processing agreement and a subprocessor list with locations are published, transcripts and recordings are stored in the EU from day one with a regional hosting option, and AWS is the named host — so my call recordings stay in Europe. The chain is not European throughout: voice transmission runs via Twilio in the USA, transcription via Deepgram and AssemblyAI in the USA, and the privacy policy names the United States, Europe and Australia as main storage locations, with EU processing of all AI and conversation data promised during 2026.
RingCentral RingEX
German customers contract with RingCentral Germany GmbH in Hamburg under German law, a data protection officer sits in Dublin, and a published data processing agreement with a subprocessor list exists, with standard contractual clauses and Data Privacy Framework certification stated as transfer safeguards. However, the privacy notice says information collected in the EEA can be transmitted to and stored on servers in the United States and Switzerland, and we found no public information on EU hosting for recordings and transcripts. The parent company is RingCentral, Inc. of the USA.
Pricing transparency
Aircall
Licence prices are public — Essentials at 30 € per licence and month, Professional at 50 €, Enterprise on individual terms — with 25 % saving on annual payment, a three-licence minimum, annual contract terms, and priced add-ons such as Analytics+ at 15 €, AI Assist Pro at 49 € and WhatsApp at 10 € per licence and month, plus per-minute and package prices for AI voice agents. We found no public information on what numbers, porting or international calls cost, on device prices, set-up fees or VAT treatment, so I cannot compute the real annual cost for my eighteen agents from the public pages alone.
RingCentral RingEX
One starting price is public — "ab nur 65 $ pro Benutzer:in" per month with unlimited minutes, quoted in US dollars on the German site — alongside a plan ladder with 100 to 2000 included minutes per user, free porting, prices exclusive of taxes and a EUR 40 late fee. A document named as German outbound call rates appears in the legal document list, but the captured pages show no per-plan prices in euros, no number or device prices, and no set-up fee or minimum term length. For eighteen agents I could not compute a real annual cost from what was captured.
