Best for a phone system you host yourself
FusionPBX is an open-source phone system on FreeSWITCH, and the software costs nothing. But you host and maintain the server, and support, call center reporting and the REST API are sold as monthly memberships from $100 to $1,000.
Who FusionPBX is for
- Fits if you can run a Linux server and want to own your phone system
- Works for hosts who want one multi-tenant PBX for many customers
Who FusionPBX is not for
- Not for you if you don't want to run a server, as you host and maintain it yourself
- Tight if you need official support, which is sold in monthly hours from $300
- Pricey if you want call center tools or the API: those sit on the $500 and $1,000 memberships
- Watch out: it sells no phone numbers or calling, so you need a separate provider
- Watch out: memberships are per individual, and Gold covers 3 employees

Keep FusionPBX, or make your own?
Keep it
To replace FusionPBX you would be making phone numbers and calls carried over the phone network. That is not a weekend's work, with an AI app builder or without one.
It costs $1,200 a year. FusionPBX is open source, so there is a third way: take its code and run it yourself.
What you could not
- Phone numbers and calls carried over the phone network.
- Fax numbers connected to the phone network.
- Speech turned into text you can trust.
- It plugs into other products, FreeSWITCH, PostgreSQL and NGINX among them, and has an API.
What this rests on. FusionPBX’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
