Checked against 3CX's own public documentation on 2026-11-11.
Fraud limits a stolen password can't lift
Minute caps on international, premium and satellite calls for every extension. Loosening any fraud control needs a password and a fresh two-factor code, and the provider sets ceilings a customer's own admin can't exceed. 3CX documents allowed-country lists and IP blacklists; we found none of these three. [19, 20, 4]
Made for Australian 000
Emergency calls are never held back by a licence limit, the emergency caller ID is checked against numbers the customer actually holds, and softphone users are warned before they rely on 000. 3CX's location-aware emergency calling is for the United States, and we found no Australian guidance. [21, 22]
Multi-tenant by design, not a mode
Every customer is its own tenant, with its own numbering, limits, branding and domain, isolated at five layers. 3CX's multi-company mode shares one extension range and one call capacity between companies, and 3CX positions it for small customers. [3, 4]
White label for partners
Sell it under your brand: your name, logo, colours, portal domain and email sender. We found no 3CX white-label programme; its apps and console carry the 3CX brand. [4, 5]
Failover isn't a premium edition
The hosted platform runs on a redundant database, an SBC pair and several call engines. 3CX failover is an AI edition feature and isn't available on Hosted by 3CX. [8]
Licensed per customer
Each customer gets its own per-seat or per-simultaneous-call plan. 3CX licenses each system by simultaneous calls, gates features such as its API, Teams and video by edition and size, and sets a maximum extension count for each licence size. [1, 2, 7, 9, 18]
