What Counts as "Call Center Software"
A modern call center platform needs more than a PBX. It needs predictive or progressive dialing, lead list management, agent status tracking, call dispositions, recording, IVR, and reporting. Many "open-source call center" projects are really just PBX projects that stop short of those features.
The Main Open Source Call Center Options
- VICIdial — Original, most deployed, active community. Predictive/progressive/preview, blended, IVR, recording.
- GoAutoDial — VICIdial fork with simpler UI. Less frequent updates. See our VICIdial vs GoAutoDial comparison.
- Asterisk (DIY) — The PBX under VICIdial. Infinitely flexible but requires extensive custom development for dialing.
- FreePBX — Great PBX, not a dialer. Usable for inbound but missing predictive outbound features.
- FusionPBX — FreeSWITCH-based PBX. Similar to FreePBX in scope — PBX, not a call center platform.
For most outbound-heavy call centers, the decision narrows to VICIdial or GoAutoDial. If you're weighing those two specifically, read our VICIdial vs GoAutoDial comparison.
Open Source Doesn't Mean Free to Run
The software license costs nothing. The server, SIP carrier, storage, backups, monitoring, patching, and sysadmin time do. Self-hosting a production VICIdial at 50 agents typically runs $400-$800/month in pure infrastructure plus the equivalent of a quarter- to half-time engineer.
That's why most mid-size call centers use hosted VICIdial — same open-source software, predictable monthly cost, no engineer on payroll.
When Open Source Is The Right Call
- You want zero per-agent SaaS fees as you scale
- You need to customize features or integrate deeply with internal systems
- You have strict data residency or compliance requirements
- You want to audit the source code
If that's you, VICIdial delivers — and our installation service can get it stood up properly from day one.
