Modern Business Communications That Work the Way You Do
A business phone system is no longer just about making and receiving calls — it's the centre of how your business communicates with customers, collaborates internally and delivers exceptional service.
Plans from $9 per user, per month

Whether your team is working from the office, remotely or across multiple locations, today's businesses need a communications platform that's flexible, reliable and ready to adapt as they grow.

- Remote & hybridOne business number on any device
- Across locationsOne system connecting every site
At calltime, we don't recommend a business phone system because it's popular, or because it's the only product we sell. As your Business Communications Partner, we recommend the cloud PBX or VoIP phone system that's the right fit for your business, then help it grow with you.
Talk to our teamEvery Business Communicates Differently. So Should Its Communications Platform.
That's why we don't start with technology.We start with understanding your business.
Choosing a business communications platform shouldn't mean being forced into a one-size-fits-all solution. Yet that's exactly how much of the telecommunications industry operates — many providers represent a single platform, so that's the platform they recommend to every customer.
Our job is different. We're not simply a telecommunications provider — we're your Business Communications Partner. Every organisation has its own people, customers, workflows and ambitions.
Before we recommend anything, we take the time to understand how your team communicates, how your customers interact with you, the systems you already rely on and the challenges you're trying to solve. Only then do we recommend a solution.

Frequently Asked Questions
Quick answers to the questions we hear most. Can't see yours? Book a free review and ask us directly.
What is a cloud business phone system?
A cloud phone system runs over the internet instead of traditional phone lines. Your team can make and receive business calls on desk phones, mobiles, laptops or inside Microsoft Teams, from the office, home or anywhere else.
How much does a business phone system cost?
Plans start from $9 per user, per month. The right price depends on how many people you have and the features you need, and we only recommend features your business will actually use.
Can we keep our existing phone numbers?
Yes. In most cases your existing numbers can move across to your new phone system, and we manage the transfer for you.
Which phone system platform do you recommend?
There isn't one best platform, only the best one for your business. We work with several leading platforms, including Access4, Dialpad and RingCentral, and recommend one after we understand how your team works.
Do we need new handsets?
Not always. Some existing phones can be reused, and many people use a mobile app or computer instead. If new devices make sense, we supply and set up Yealink and Poly phones and headsets.
