Hosted PBX

The name describes the arrangement: the PBX — the brain that answers calls, plays menus, and routes to extensions — is hosted by the provider rather than installed in your building. Your desk phones and apps reach it over your internet connection, you administer it in a web dashboard, and the provider owns the hardware, the upgrades, and the uptime.

If that sounds identical to a cloud PBX, that's because it is. 'Hosted PBX' is the older label from the industry's first wave of moving phone systems off-premises; 'cloud' became the fashionable word later. A few vendors draw fine distinctions — using 'hosted' for dedicated single-customer setups and 'cloud' for shared modern platforms — but in the market you'll shop in, the terms are interchangeable.

Mostly so vocabulary doesn't cost you money. You'll meet all three labels — hosted PBX, cloud PBX, cloud phone system — often describing the same product at different prices depending on which term the vendor thinks you searched for. Comparing a 'hosted PBX quote' against a 'cloud phone system plan' as if they were different categories is exactly the confusion the naming invites.

The real decision underneath the labels is the one that matters: rent the phone system as a service, or own equipment on site. For nearly every small and mid-sized business, renting wins on cost, maintenance, and resilience — whatever the vendor calls it.
