VoIP carries the call.
The PBX decides what happens to it.

A PBX controls users, extensions, routing, hunt groups, queues, voicemail and call behaviour. VoIP provides the way voice calls travel over IP networks — a modern hosted PBX will often use VoIP technology underneath it. Historically, PABX meant Private Automatic Branch Exchange, while PBX referred more broadly to a private telephone exchange. Today the terms are used interchangeably to describe a business phone system.

— The problem

Phone systems get complicated
one change at a time.

What started as a simple setup can gradually become extensions nobody remembers, old routing rules and unclear ownership when calls stop working. Common signs the PBX needs attention:
01

Calls regularly reach the wrong person

02

Users can't easily move between locations

03

Adding or removing extensions is difficult

04

Multiple offices use separate phone systems

05

Call flows no longer match operating hours or teams

06

Voice administration relies on one person or supplier

—

A phone system should reflect how the business operates now — not how it was structured when the PBX was first installed.

Common Challenges:

The system is ageing or difficult to support

Nobody has a clear picture of how it's configured

Voicemail boxes nobody monitors

Numbers pointing to the wrong people

Suppliers needed for every small change

—

Small changes shouldn't need a supplier call every time.

— What we do

We bring structure
to how your calls are managed.

A PBX is the system that decides where business calls go and how users interact with them — extensions, routing, hunt groups, queues, voicemail, business hours and auto attendants. Zinia designs, implements and manages PBX solutions around how your business actually operates. Zinia also provides call recording and compliance solutions for voice and Microsoft Teams.

We bring:

Hosted and cloud PBX platforms

Extension, routing and hunt-group configuration

Call queues and auto attendants where supported

Business-hours and after-hours routing

Multi-site voice architecture

Ongoing adds, moves and changes

— Who this is for

Built for organisations that
need more control over their calls.

Business PBX can suit organisations that:
Are replacing an ageing PABX
Operate multiple offices
Regularly add or move users
Support remote or hybrid users

— Outcomes

Easier to reach. Easier to manage.
Built to scale.

Clear routing. Simple changes. One accountable partner.
Callers reach the right person, faster
Ordinary phone-system changes, simplified
Consistent voice environment across sites
Clearer ownership across phone, voice and connectivity

Users, numbers, departments and how calls should move through the business.

02

Design

Define extensions, routing, hunt groups, queues and required functionality.

03

— FAQ

Frequently asked questions
about business PBX systems

A PBX, or Private Branch Exchange, is a business phone system that manages calling functions such as extensions, incoming numbers, routing, hunt groups, queues and voicemail.
A hosted PBX delivers phone-system functionality from a hosted platform rather than relying entirely on traditional PBX equipment located at the business premises.
A hunt group allows incoming calls to be presented to a defined group of users according to the configured calling pattern.
Yes. Zinia’s managed hosted PBX/VoIP framework includes operational support such as call-flow changes, hunt groups and user adds, moves and changes, depending on the contracted service.
PABX stands for Private Automatic Branch Exchange. In modern business telephony, PBX and PABX are commonly used to describe the same general type of business phone system.
A PBX controls how business calls are handled. VoIP is the technology that allows those calls to travel over an IP network. See Business VoIP.
Yes, depending on the platform and network design. Hosted PBX environments can support users and extensions across multiple sites within a common phone-system architecture. For multi-site connectivity, SD-WAN can help manage how traffic uses the available links.
A hosted PBX generally depends on connectivity between users and the voice platform. Backup connectivity can form part of the resilience design, though exact behaviour depends on the platform.

Does your phone system
still match the way your business works?

If your users, offices and customer-service requirements have changed but your PBX hasn’t, it may be time to review how calls move through the organisation.
