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 Office Manager
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.

Criterion by criterion
Calling, numbers & call routing
Aircall
Porting is promised by the vendor's own team, and numbers in over 100 countries, an IVR directory, queues, ring groups by skill, time-based routing, three-digit extensions, call pickup and pause-resume recording are all described, which covers my greeting-and-queue during deadline weeks. But we found no public information on emergency calls to 110 and 112 with a caller location, on fax, on porting timelines, and voicemail is documented with customised greetings and app notifications rather than delivery by email.
RingCentral RingEX
Free porting with a stated seven to fourteen business-day window and a documented checklist (recent bill, account details) is exactly what I need for the number on our thirty-year-old letterhead. Separate greetings for business hours, after-hours and holidays, a drag-and-drop IVR, queues with hold music, ring groups, voicemail-to-email transcription, internet fax and emergency calling documented for Germany down to the area-code rule are all described. We found no public information on number blocks, call park or busy lamp fields.
Apps, desk phones & Microsoft Teams
Aircall
iOS and Android apps, browser access, presence, business calls on mobile without exposing the private number, a GSM fallback, and a Microsoft Teams integration with presence sync and outbound calls from Teams are all described. For keeping our desk phones, however, we found only a generic mention of VoIP hardphones; we found no public information on makers such as Yealink or Snom, automatic provisioning, or devices for sale or rent.
RingCentral RingEX
Desktop, mobile and browser apps with presence, device switching and Teams telephony through Direct Routing with Microsoft certification are documented, which suits our staff. Yealink desk phones are covered, but only via manual provisioning in the phone's web interface; we found no public information on a list of supported desk and DECT phones with automatic provisioning, or on devices sold or rented.
Call centre, analytics & AI
Aircall
Queues with a callback option, a live view of who is free and how long callers wait, statistics per agent, leaderboards, a power dialer and recordings for coaching are documented, and the AI side is broad: transcription, summaries, an AI receptionist in 38 languages, and SMS and WhatsApp beside calls. Whispering appears in the Professional plan, but we found no public information on listen-in and barge or on scheduled, exportable reports.
RingCentral RingEX
Skills-based routing, whisper and barge-in, preview, progressive and predictive dialers, over 250 reports with live dashboards, AI transcription, summaries and sentiment, an AI receptionist and SMS beside calls are all described — more than our deadline-week queue and greeting needs. We found no public information on callbacks from the queue or on the languages of the AI transcription.
CRM integration, API & administration
Aircall
Over 250 native integrations including HubSpot, Salesforce, Zendesk and Pipedrive with click-to-dial, screen pops and automatic call logging, a documented REST API with webhooks across numbers, users, contacts and calls, plus user roles, two-factor authentication and single sign-on with SCIM at Enterprise are all described. We found no public information on SIP trunks for an existing PBX, audit logs, or bulk user import.
RingCentral RingEX
Click-to-call, caller pop-ups and automatic call logging are described for Salesforce, Microsoft Dynamics, Zendesk and Zoho, alongside single sign-on with enforced multi-factor authentication, SCIM user provisioning, an audit trail, configurable roles, several sites in one account and a documented API platform. We found no public information on partner or reseller accounts, and SIP trunks for a named PBX appear only as a bring-your-own-carrier mention.
Reliability, call security & telecoms compliance
Aircall
A public status page with 90-day component uptime and incident updates, a stated availability of 99.95 percent, TLS and SRTP encryption, regular third-party penetration tests with a bug bounty, and a committed annual SOC 2 Type II audit give me reasonable comfort for a bad day. We found no public information on emergency calling for home offices, on registration with the German regulator, or on a published SLA with credits — the SLA is named only as an Enterprise-level item.
RingCentral RingEX
A 99.999 percent availability figure with a nineteen-quarter uptime record, TLS and SRTP encryption, and ISO 27001, SOC 2 and BSI C5 attestations for RingEX are published, plus emergency-calling terms covering Germany and the smartphone app's hand-off to the native dialer — the C5 attestation matters to a tax office. We found no public information on a service-level agreement with credits, a public incident history, Bundesnetzagentur registration or toll fraud protection.
European sovereignty
Aircall
The contracting entity is a French company in Paris, a data processing agreement with standard contractual clauses and a CNIL-registered data protection officer are published, and a subprocessor list with countries is maintained. That list shows voice transmission through Twilio in the USA and transcription through US providers, the main storage locations include the United States and Australia with transfers to India, and complete EU storage of AI and conversation data is announced for 2026 rather than in place today, so the chain is well disclosed but not European end to end.
RingCentral RingEX
German customers contract with RingCentral Germany GmbH in Hamburg under German law, with a published data processing agreement, a subprocessor list and standard contractual clauses as transfer safeguards. The privacy notice states that information collected in the EEA may be transferred to and stored on servers in the United States and Switzerland, and we found no public information on where call recordings and voicemails would be hosted.
Pricing transparency
Aircall
The plans are public at 30 €, 50 € and custom per licence and month with their inclusions, and add-ons are priced openly — analytics, WhatsApp, AI Assist Pro and AI voice agents down to pay-as-you-go at 0,25 € per minute, with a 25 percent annual discount and a three-licence minimum. We found no public information on what a number or a port costs, per-minute prices for calls beyond the included minutes, device prices, set-up fees or VAT treatment, so the partners could not compute our annual bill from these pages alone.
RingCentral RingEX
Four plans are shown with their included minutes per user (100, 500, 1000, 2000) and a starting price of 65 $ per user per month with unlimited minutes, plus free porting, one free virtual number, prices exclusive of taxes, a EUR 40 late fee and thirty-day payment terms. We found no public information on number, device or add-on prices, set-up fees, the minimum term, or the per-minute rates outside the included minutes beyond a listed outbound-rate document for Germany.
