VoxBox · from Binary Systems

Build your own communication infrastructure.

Every call your organization makes is a conversation about its future. Right now it may be riding on someone else’s servers, under someone else’s terms. VoxBox is a complete phone system, built on Asterisk, that runs on your server, on your network, under your control. Binary Systems builds it with you.

Built on Asterisk · Web-based management · Yours to run

01 · The problem

You don’t rent your boardroom.
Why rent your voice?

Somewhere along the way, the phone system became a subscription. The convenience was real. So was the bargain: your calls, your voicemail, your call records and your roadmap moved onto somebody else’s servers, under somebody else’s terms.

Rented

Their servers.

Your conversations travel through infrastructure you don’t own and can’t walk up to.

Rented

Their terms.

Retention, access and pricing live in a contract you didn’t write, and it can change on their schedule.

Rented

Their roadmap.

Features arrive, change and disappear when the provider decides. Your phones, and your people, follow along.

Renting is fine for a convertible on vacation. It’s no way to run an organization’s voice.

02 · The promise

Own the line.

  • Your server.
  • Your network.
  • Your data.
  • Your call.

Privacy

Calls, voicemail and call records live on hardware you control, inside walls you choose. Who gets access is your decision, not a line in someone else’s policy.

Control

You decide when things change. It’s been the VoxBox philosophy from the start: a phone system shouldn’t be upgraded on a whim, but it should be watched very closely.

Destiny

Built on Asterisk: open and standard. No proprietary lock-in, no semi-open trapdoor. Where your communications go next is your call.

“Most of all, users and managers can feel confident that they are not locked into a proprietary or semi-open solution.”From the original VoxBox page, Binary Systems, Inc.

03 · What VoxBox is

A complete phone system.
Yours, down to the source.

VoxBox is Binary Systems’ Asterisk-based PBX distribution. It packages the call engine, a web-based management interface and the system tools to run them, so the major components of your phone system just work. No bling, no mystery.

The VoxBox cube

Built on Asterisk

Asterisk is compiled from source for your hardware: Asterisk 22 LTS by default, or Asterisk 23.

Web-based management

Administer your PBX from a browser. Your users get their own User Control Panel.

System tools included

Webmin handles the operating system, right alongside the phone system.

Doors locked at install

The installer sets up a firewall and port knocking, so the front door isn’t left open.

Keep your desk phones

Endpoint Manager comes with Polycom SoundPoint templates, so a working phone fleet can stay on the desk.

Runs where you put it

Debian 13 or Rocky, Alma and other RHEL-family servers, on bare metal or as a virtual machine, including Harvester.

05 · How we build it with you

You own it.
We build it with you.

Owning your communication infrastructure doesn’t mean doing it alone. Binary Systems takes you from rented to owned, one deliberate step at a time.

  1. 1

    Assess

    We map your sites, lines, phones, carriers and the people who depend on them. Then we tell you plainly what owning it takes.

  2. 2

    Build

    We build your VoxBox on your hardware or your virtualization platform, configured around how your organization actually calls.

  3. 3

    Deploy

    We cut over with you, phones and people included, and hand you the keys. The admin credentials are yours.

  4. 4

    Support

    We stay on the line for patches, backups, monitoring and changes, so your system is watched closely and changed deliberately.

Decades in telecom and networking.
The original BSI, since 1977.

Binary Systems was founded in 1977. Its early SCADA systems used digitized ADPCM voice to announce alarms over telephone networks, and the name VoxBox goes back to BSI’s own voice-synthesis development system of the late 1970s. Today BSI works from Richardson, Texas, in the Telecom Corridor.

  1. 1977Binary Systems is founded, building embedded control and communication systems.
  2. Late ’70sThe first VoxBox: voice synthesis and voice-enabled SCADA.
  3. LaterLong-haul transmission devices and VAIN, an AIN-based softswitch.
