Construction & trades

Cloud PBX for construction and trades teams

Voxbi is a business phone system that runs from an app on a smartphone, so crews on site, site managers, and office staff share one business number without a desk phone or an office install. Set it up yourself, reassign extensions as people move, and keep your data in the EU.

  • Runs from a mobile app, no desk phones
  • One business number on every van and invoice
  • EU-hosted by default

Is Voxbi a fit for your trades business?

A ten-second check before you read on.

Good fit if you

  • Have staff on site or in the field for most of the working day
  • Want to stop personal mobile numbers appearing on invoices and vans
  • Need out-of-hours calls to route away automatically after working hours
  • Have two or more people sharing responsibility for inbound calls

Worth a conversation first if you

  • Are a sole trader with very low call volumes
  • Work mainly in areas with poor mobile or internet coverage
  • Already run all your comms through a job management platform
  • Run a seasonal business active for only a few months a year

Why a field-based team outgrows personal mobiles

The director's mobile is the business number

A personal number is printed on every invoice and business card, so client calls land at 20:00 and on weekends with no way to switch them off.

The office can't reach people on site

When a caller wants a site manager, office staff text a personal number and ask them to call back. There is no extension to transfer to.

When someone leaves, the clients leave too

Clients keep calling the site manager's personal mobile after they go. The number, and the relationship, walk out the door with them.

What changes on day one

Same numbers, no hardware on site.

  • Personal mobile number printed on every invoice and van One business number on all materials, vans, and marketing

Frequently asked questions

Can we run the business without any desk phones?

Yes. The whole phone system can run from the mobile app on each team member's smartphone, with no desk phones, no wiring, and no office install. This is the most common setup for construction and trades. Adding a desk phone in the office later is optional, not required.

What happens when someone is in an area with poor mobile signal?

The app works on both mobile data and Wi-Fi, so on most sites it works as normal. In underground or shielded areas, calls can route to voicemail automatically or reroute to a colleague with signal, and fixed-mobile convergence means the office phone still rings.

Can we keep our existing business number when we switch?

Yes. You can port your existing number from your current operator, and it keeps working until the switch completes. If your current number is a personal mobile, it can often be ported too, or you can keep it and adopt a new business number.

What happens to our number when an employee leaves?

Nothing changes for the business. The extension is reassigned to a colleague in a couple of minutes from the dashboard. Because the number belongs to the business, not the individual, client calls keep reaching the team. This is the biggest difference from using personal mobiles.

Can we set Voxbi up ourselves, without an IT project?

Yes. Voxbi is self-serve: every team member installs the app, you add users and numbers, and you build your call flow from the dashboard. Support is available if you want a hand, but no engineer visit is required.
