The phone system your staff will actually like

OnePBX is a complete business PBX on Asterisk 22. Instead of static configuration, every call is routed live from the database. Ring groups, time conditions, IVR menus and call rules take effect the moment you save them. Administrators get one console; every staff member gets their own phone portal and browser phone.

What you can build

Answer: an IVR or AI receptionist greets callers in a natural voice.
Route: callers reach ring groups, queues or extensions, depending on the time of day and the caller.
Handle: staff answer on desk phones, the browser phone or OneCall, with a caller pop-up showing a photo.
Follow up: callers can leave voicemail, and the operator console handles transfers and parks.

Visual IVR designerDrag-and-drop call flows with auto-layout, zoom and minimap.
Text-to-speech promptsType a greeting and the system speaks it in English, Swahili, French, Arabic, Portuguese, Spanish, German or Italian. Voices run locally (Piper), so no studio recording is needed.
AI receptionist in 7 languagesCallers say where they want to go, in English, French, Spanish, German, Italian, Portuguese or Arabic, and it understands and routes them, using on-server speech recognition.
Browser phoneA WebRTC softphone in any browser, plus a personal portal at /me.
Operator consoleLive extension view with transfer, park, voicemail and hang-up.
Call routingRing groups, queues, time conditions, inbound and outbound routes.
Voicemail & pop-upsVoicemail, plus caller pop-ups with extension photos.
