Self-Hosted PBX vs Cloud PBX: Which Fits Your SMB?

For most small businesses, a cloud PBX beats a self-hosted PBX because it removes the server, the security patching and the on-call burden while keeping the same call-handling features. A self-hosted PBX like FreePBX or Asterisk gives you total control and no per-seat fee, but you own the hardware, the updates and the security. A cloud PBX runs in the provider's data center for a flat per-seat price, so you get IVR, routing and voicemail without a box to maintain.
What is a self-hosted PBX?
A self-hosted PBX is a phone system you run yourself, usually FreePBX or raw Asterisk on a server or VPS in your office or cloud account. You install it, configure SIP trunks and extensions, harden it against attacks, and apply every update. It is powerful and cheap on paper, with no per-seat license, but the real cost is your time and the risk if it is misconfigured.
What is a cloud PBX?
A cloud PBX is a business phone system delivered as software from a provider's cloud. Extensions, auto-attendant, IVR, call routing and voicemail all live off-site, and your team makes and takes calls from apps. There is no server to buy, secure or patch, and you pay per seat. See our full Cloud PBX platform for the feature set.
Self-hosted vs cloud PBX: the real tradeoffs
- Cost: Self-hosted has no per-seat fee, but you pay for the server, your setup time and ongoing maintenance. Cloud PBX is a predictable per-seat price with no hardware. See cloud PBX pricing.
- Maintenance: With FreePBX you own upgrades and module breakage. A cloud PBX is updated for you, with no downtime to schedule.
- Security: A self-hosted PBX exposed to the internet is a target for SIP fraud if it is not locked down. A managed cloud PBX handles SIP hardening and STIR/SHAKEN for you.
- Control: Self-hosted wins on deep customization and dial-plan control. Cloud PBX trades some of that for simplicity most SMBs prefer.
- SIP flexibility: Good on both, if the provider does not lock you in. Dialerportal lets you bring your own SIP trunk, unlike systems that force preferred carriers.
Which should your SMB choose?
Choose self-hosted if you have in-house telephony skills, want maximum control, and have the time to secure and maintain the system. Choose a cloud PBX if you want a professional phone system without a server or a security project, which is most small teams. If you are weighing hosted versus cloud specifically, our hosted PBX vs cloud PBX guide breaks down the nuance.

Frequently Asked Questions
Is a self-hosted PBX cheaper than a cloud PBX?
On the license it is cheaper, since FreePBX has no per-seat fee. But once you add the server, your setup time, maintenance and security, the total cost of ownership often matches or exceeds a cloud PBX. A managed cloud PBX from $19 per seat has no hardware or hidden upkeep.
Is FreePBX secure?
FreePBX can be secure, but only if you harden it correctly, restrict SIP access and patch it promptly. An exposed, misconfigured PBX is a common target for toll fraud. A managed cloud PBX moves that risk to the provider.
Can I keep my numbers if I move from self-hosted to cloud?
Yes. We port your existing business numbers for free in 24 to 48 hours with no downtime, and manage the carrier paperwork for you. Ask our dedicated support team to schedule the cutover.
Can I bring my own SIP trunk to a cloud PBX?
With Dialerportal, yes. We do not lock you to a preferred carrier, so you can bring the SIP trunk you already use or switch to ours. That flexibility is a common reason teams leave more restrictive systems.
