VoicerOnePBX Documentation
Everything you need to install, administer, use, and extend VoicerOnePBX — a complete, self-contained business phone system that runs on a single Mac.
VoicerOnePBX turns one Mac into a complete business phone system — technically an IP-PBX, meaning a phone system that runs over your internet/office network instead of old copper phone wiring. It registers desk phones and softphones (phone apps that run on a computer or in a web browser), connects to phone-service providers over SIP or IAX2, answers incoming calls with automated menus, groups of phones and call queues, runs conferences, sends and receives faxes, transcribes calls and voicemail, and lets you drive it all from a modern admin screen — or from your own software through a documented interface.
You don't need a telecom background to follow these guides. Wherever we use a technical term you'll see it underlined with dots — hover or tap it for a one-line plain-English definition, or browse them all on the Glossary page.
These docs use a drill-down structure: start with an overview, pick the area you care about, and each step down gives you progressively more detail — right down to firewall ports, provisioning file formats, and API payloads.

What makes it different
Self-contained
One signed, notarized macOS app. No Asterisk, no Linux server to babysit, no external database.
Private by design
Your calls, recordings and transcriptions stay on your Mac. Transcription runs on-device.
Standards-based
Uses the same open standards the phone industry does — SIP and IAX2 for calls, standard G.711/G.722 audio codecs, and T.38 for fax — so it works with mainstream phones and providers.
Proven at scale
Load-tested to 300 concurrent calls (600 legs) on a single Mac with a one-hour endurance soak.
