Quick answers

What does PBX mean?
Private branch exchange. It's the switchboard that takes calls to your business number and sends them to the right person or department.
What makes a PBX virtual?
The switchboard runs on the provider's servers instead of hardware in your office. You manage it online.
Do I need extensions?
Usually not. Small teams work better with ring groups, direct routes, and a shared inbox. Add a menu only if callers genuinely need one.

Route by purpose, time, and who's free

One public number can reach several people without giving out anyone's personal mobile.

A clear path for every call
Send calls to a person, a group, voicemail, a text back, or Molly. Add a fallback for when the first option doesn't answer.
Schedules that switch themselves
Evenings, weekends, bank holidays, and an on-call rota. The route changes on time without anyone touching it.
Change it yourself
Add a new starter or move the on-call phone from the app. No engineer and no handset programming.

Worth knowing

The old landline network switches off in January 2027
Openreach is retiring the analogue phone network on 31 January 2027. A business still on a traditional landline needs a digital replacement before then. Moving early means you choose the timing, not your provider.
