PBX with a strong UCaaS app suite, available self-hosted or on 3CX-hosted instances. Per-call concurrent licensing.
Both platforms can power a hosted phone service, but they're built for different shapes of business. SimuWave is a true white-label, multi-tenant platform built from day one for MSPs — your customers see your brand on your subdomain, never ours, and you run many tenants from a single pane of glass. 3CX is a single-tenant PBX with polished apps and a "Branded Apps" add-on for partners; resellers typically run one 3CX instance per customer.
SimuWave is for
MSPs and resellers who want true white-label — your customers (and their customers) never see SimuWave. Custom subdomain, your branding, your support email. One platform, many tenants, modern visual call flow designer with live monitoring.

What only SimuWave has
Features built into SimuWave that you won't find — or won't find at the same depth — in 3CX.
Live calls light up the canvas as they route. Open the designer for a busy line and watch active calls move through nodes in real time, with intensity colors and pulsing edges. There's no equivalent in 3CX — its switchboard view shows extension status, not a routing-graph overlay.
Multi-tenant white-label without an add-on. Every customer on their own branded subdomain, your colors, your support email — under one platform. 3CX gates Branded Apps behind an add-on tier and resellers typically run one instance per customer.
Outage failover as a drop-in node with auto-detect, configurable grace and recovery periods, and email alerts. 3CX requires manual failover routing rules.
Toggle switches with feature code, BLF, AND custom spoken announcements. Dial *60 to flip routing, the desk-phone BLF reflects state, and the system speaks your custom phrase ("Now in night mode," "Route to Frankie activated"). 3CX has Day/Night/Holiday modes; none of the other layers.
Multi-carrier U.S. DID inventory built in. Find and provision local-city numbers across major metros without a separate trunk-shopping trip. 3CX is bring-your-own-trunk.
Live transcription stream into the dashboard during the call — not after.
PIN gate as a drag-and-drop node for protected branches in any flow.
Bottom line
For MSPs and resellers, SimuWave is built for the white-label, multi-tenant job from day one — every customer on a branded subdomain, one platform, modern visual flow designer with live activity overlay, and operational nodes (outage failover, toggle switches with TTS, PIN gates) that are first-class features instead of bolt-ons.
