The best 3CX alternative
for small business.
3CX is powerful if you have IT to run it, but it puts hosting, SIP trunks, and maintenance on you. Frontdesk is fully managed, answers every missed call, and charges one flat price. Here is the full breakdown.
3CX is a PBX you have to run. Most small teams should not.
3CX is a flexible PBX you self-host or have hosted, with per-system licensing. Power users love the control. The cost shows up in the work: provisioning servers, arranging SIP trunks, configuring desk phones, and maintaining it all. And like any PBX, it does not answer calls on its own, so missed calls still go to voicemail.
Frontdesk is a fully managed cloud phone system with an AI receptionist built in. It answers the calls your team cannot, qualifies the lead, books the appointment, and writes the whole conversation back to your CRM. Flat monthly price, unlimited seats, no servers to run.
This guide compares 3CX, RingCentral, and Frontdesk on cost of ownership, inbound coverage, and CRM sync so you can pick the right fit for a small team in 2026.
Everything a great 3CX Alternative does. At 1/10th the cost.
AI receptionist answers every missed call
3CX gives small businesses a self-hosted or hosted PBX. Frontdesk adds an AI receptionist that picks up the calls nobody catches, books appointments, and texts you a summary.
No servers, no SIP trunk wrangling
3CX often means provisioning a PBX, SIP trunks, and desk phones yourself. Frontdesk is fully managed cloud with nothing to host or maintain.
Calls, texts, and email in one inbox
Customers reach you on any channel and you see a single timeline per contact instead of a PBX console and separate tools.
Native CRM sync
Every call, text, and voicemail logs to the contact in HubSpot, Salesforce, or Pipedrive automatically, without configuring a connector.
Lead qualification on the call
The AI asks the questions your team would, scores the lead, and routes hot ones to a human while logging the rest.

Port your existing number or pick a new one, train Frontdesk on your business, and start answering calls in under 30 minutes.
