A hosted PBX moves the private branch exchange off your premises and into a provider's data center. You get extensions, call routing, voicemail, and auto attendants delivered over the internet, with no box to install or maintain.
It is the cloud version of the traditional PBX. The business gets enterprise call handling on a subscription, scales lines in software, and skips the upfront hardware cost entirely.
Frontdesk gives you a business number answered by an AI receptionist that picks up every call, qualifies the caller, books the appointment, and logs the whole conversation to your CRM.
