3CX review

3CX is a business phone system and contact center platform. Its homepage says customers can run it as a 3CX-hosted service, self-host it, or deploy it on-premise. The license is priced per system rather than per user, with license sizes based on simultaneous calls.

The product combines standard phone-system features with AI tools. 3CX lists AI agents for call routing, screening, and round-the-clock support, plus an AI receptionist and personal assistant. Its contact center includes sentiment analysis, and AI transcription is available in the mobile apps. The platform also connects with Salesforce, HubSpot, Zoho, Zendesk, and Freshdesk.

That mix makes 3CX worth considering if you want phone and contact center functions under one system. The per-system model is not automatically cheaper: the license size, deployment choice, and separate hosting charge all affect the bill.

The main appeal is breadth: 3CX combines phone-system and contact center functions with AI features, while offering hosted, self-hosted, and on-premise deployment, according to its homepage. That gives buyers more control over where the system runs than a hosted-only setup would.

The feature set includes:

• AI agents for call routing, screening, and 24/7 support.
• Contact center tools with AI-powered sentiment analysis, plus call transcription in mobile apps.
• An AI receptionist and personal assistant.
• Integrations with Salesforce, HubSpot, Zoho, Zendesk, and Freshdesk.

The pricing model may also suit teams that prefer a system license over a per-user bill. According to the pricing page, Basic starts at $300 per year, Pro at $395, and AI at $575; those are starting annual license prices, not monthly bills. The listed license sizes run from 8 to 1,024 simultaneous calls. For licenses of 24SC and above, the pricing information lists an extra 10% discount on renewals of three or more years. Hosting is separate, so compare the total cost rather than the license alone.

The headline prices can understate the cost. The pricing page lists Basic at $300 per year, Pro at $395, and AI at $575, billed as a flat annual fee per system. The displayed monthly equivalents—$25, $32.92, and $47.92—are annual prices divided by 12, not monthly billing. Hosting costs another $295–$1,995 per year where available, and some license sizes show hosting as unavailable. Prices exclude tax or VAT.

The license is sized by simultaneous calls, not by named users, and the listed range is 8–1,024 simultaneous-call licenses. Buyers should confirm the required size and hosting availability rather than assume the starting price covers their setup.

There is also reseller risk to weigh. In Reddit discussions, some partners report changing sales or partnership terms, support frustrations, and customers moving to alternatives. Those are user reports, not proof that every buyer will face the same issue. Still, if a reseller manages your phone system, ask who supports it and what happens to your service if that relationship changes.

The pricing page lists annual, per-system licenses—not monthly contracts. Basic starts at $300 a year, or $25 per month equivalent. Pro starts at $395 a year ($32.92 equivalent), and AI starts at $575 a year ($47.92 equivalent). The step from Basic to Pro is $95 a year; Pro to AI adds another $180. These are starting license prices, not per-user rates, and listed license sizes range from 8 to 1,024 simultaneous calls.

Hosting costs extra: the listed range is $295–$1,995 a year where available, and hosting is unavailable for some license sizes. That can change the total, so compare the license and hosting costs for your required capacity before switching. The annual fee is billed as one flat payment per system; monthly equivalents are just annual prices divided by 12. Prices exclude tax or VAT. The pricing details also list a 10% discount on three-year-or-longer renewals for licenses at 24SC and above; hosting does not get that discount.

3CX offers hosted, self-hosted and on-premise deployment, so switching effort will depend partly on the setup you choose and the phone system you have now. Before committing, map your call flows, numbers, devices and CRM connections, then ask the partner or 3CX what will transfer and what must be rebuilt. The published material names integrations with Salesforce, HubSpot, Zoho, Zendesk and Freshdesk, but does not specify migration tools or supported data-export formats.

Treat that gap as a procurement question, not a promise of portability. Confirm how you can export contacts, recordings, transcripts, call data and configuration before signing, and check what happens if you change providers or deployment types. The review brief flags partner uncertainty as a concern, but no Reddit posts or comments were published here, so we can’t substantiate what users say makes them leave. Ask for the migration and exit terms in writing, including any partner-dependent support.
