The short answer
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.
