Use case
Corporate: one internal network across branches
A company with offices in several cities shouldn't pay for calls between its own sites or have a different phone in each one. With a cloud PBX, every branch dials the others by extension, at no cost, and they share the same attendant menu.
Updated: 17 October 2026
The situation
Each branch grew with its own PBX and its own numbering. Calling from one office to another costs like an external call, the attendant menu is different everywhere and there's no way to see the company's phone operation as a whole.
What we propose
- A single cloud PBX for the whole company: each site is a range of extensions within the same network.
- Extension dialling between offices, at no call cost, whatever city they're in.
- One attendant menu and schedule, with forwarding between sites when one can't answer.
- Over SIP trunks if you want to keep equipment at a site, with portability of the numbers you already have.
What you gain
One internal network across all branches, no paying for calls between sites, with consistent service and a single view of the operation. Managed from a panel, with no equipment in each office.
Frequently asked questions
Can I keep each branch's numbers?
Yes. We port the numbers you already have and keep them running on the new PBX, without your customers noticing the change.
Do I have to replace all the phones?
Not necessarily. You can start with app and browser, add IP phones where needed and keep equipment via SIP trunk where it makes sense.
Do you have offices in several cities?
We'll show you how to join all your branches into one internal network, with extension dialling between sites and the same attendant menu.
