Business VoIP Solutions

Business calling that works
with how your organisation works now.

Voice no longer needs to depend on traditional phone lines or an isolated office telephone system. Business VoIP allows calls to run over IP networks, supporting modern offices, multiple locations, remote users and cloud-based communications. Zinia helps businesses implement and manage VoIP solutions around their users, connectivity and wider communications environment.

VoIP isn't just a
phone-system decision.

In a traditional environment, calls rely on dedicated telephony infrastructure. With VoIP, voice traffic travels across your network — from the handset, over your LAN or Wi-Fi, through the voice platform, out over the internet or carrier network, to its destination. That makes the quality of the wider technology environment part of the call itself — which is where Zinia’s connectivity and network capability change the conversation.

— The problem

Business voice has changed.
Many phone environments haven't.

Traditional or fragmented voice environments can create problems such as:

Multiple phone systems across different sites

Difficulty adding or moving users

Limited flexibility for remote or hybrid work

Poor visibility into call quality

Voice suppliers separated from the network provider

Old hardware becoming difficult to support

—

Modern business voice should be easier to manage than the phone systems it replaces.

Common Challenges:

Recurring issues passed between the ISP, PBX provider and IT team

Call-routing changes taking too long

Poor call quality with no clear cause

Remote and hybrid workers left without reliable calling

Numbers and extensions hard to manage centrally

—

When the network struggles, so does the phone system.

— What we do

We design voice
around the network it runs on.

VoIP carries voice calls over your IP network instead of traditional phone lines — supporting office desk phones, softphones, remote users, multiple locations and hosted or cloud communications platforms. Zinia designs, implements and manages business VoIP so the phone system works with the network underneath it, not around it. Zinia also provides call recording and compliance solutions for voice and Microsoft Teams.

Frequently asked questions
about connectivity and communications

What is VoIP?

VoIP stands for Voice over Internet Protocol. It’s technology that allows voice calls to be carried over IP networks rather than relying entirely on traditional telephone-line infrastructure.

What's the difference between VoIP and PBX?

VoIP is the technology that transports calls across an IP network. A PBX manages business calling functions such as extensions, call routing, hunt groups and voicemail.

Will VoIP work if our fibre goes down?

It depends on the network design. Where appropriate backup connectivity is available, voice services may use an alternative path — though active calls may still be affected during failover.

Can VoIP support remote workers?

Yes, where the selected platform supports appropriate remote endpoints such as softphones, mobile applications or remote IP devices.

Is VoIP suitable for business?

Widely, yes. VoIP suits organisations that need flexible calling across users, offices or distributed locations. The right solution depends on connectivity, network quality, calling requirements and support needs.

Does VoIP need an internet connection?

Hosted VoIP services generally depend on network connectivity to reach the voice platform or carrier. The exact architecture depends on the solution being used.

What affects VoIP call quality?

Latency, jitter, packet loss, congestion, Wi-Fi performance, network configuration and the quality of the underlying internet connection.

Can we keep our existing phone numbers when moving to VoIP?

Existing numbers can often be ported to a new voice service, subject to provider, number type and regulatory or carrier requirements. Zinia confirms eligibility as part of the migration assessment.
