1500+ Happy Customers & Counting

I recently had a new VC installed from the team at Prosum. David Colletta and his team were not only professional with the installation, but at all times, the communication was second to none from them to see at each step where we were at. The installers were brilliant, and to top it off, they cleaned after the installation leaving us nothing to do. How refreshing this was. Again, I cannot speak highly enough of the team at Prosum; their professionalism was second to none, and their on-time approach was exactly that on time! Please do yourself a favour and get the team out there to look at what your needs are for the business, big or small. They have it all! Well done and thank you.

Yolanda Di Ludovico,

FIRST SUPER

We needed an experienced ICT VoIP provider that could implement a new telephony solution without affecting existing telephony services and business operations. After reviewing other providers, we selected PROSUM who was able to successfully migrate all our users onto the new NEC platform and complete the project in a timely manner. PROSUM continue to provide support for our NEC Telephony and Contact Centre environment and I would recommend their services to other organisations and enterprises.

ICT INFRASTRUCTURE & SERVICE DELIVERY MANAGER - VICTORIAN CYTOLOGY SERVICE LIMITED

We are constantly looking to continuously improve the way we do business and service our customers and distributors within our customer service operations. This is why we selected PROSUM as our telephony and contact centre provider. Their experience means we have a VoIP provider we can rely on to provide and maintain our telephony and contact centre environment.

Aitken Real Estate had to move office and sought David Colletta of Prosum advice about switching our telephony to the cloud. Extremely helpful, no-nonsense information and can get the job done. Their tech Antoine was sensational. No delays, no problems. Highly recommend!

Stephen Aitken,

AITKEN REAL ESTATE

Thanks to the PROSUM team for the successful migration of the Brisbane phone system. A great deal of planning and hard work in the preparation resulted in a smooth migration with zero downtime to the business – a reflection on the dedication and preparedness to the project. Thank you.

Prosum is your one-stop shop for all your business communication and collaboration needs. 

Everything you need under one roof

From unified communications and customer engagement solutions to connectivity and ongoing support – we've got you covered. 

Simplicity and convenience

One provider, one account manager, and one monthly bill for phone, internet and 1300 & 1800 numbers. 

Competitive pricing

We provide a fixed quote guarantee for project work. Our Telco and implementation costs are 10-30% cheaper than our major competitors. 

Tailored solutions

We understand your business is unique. That’s why tailor solutions built on years of experience to remove your business pain points. 

All-around experts

We do more than phone systems, we bring unique skills that provide real value to your business. 

Fast response times

No voice menu and waiting on the phone for hours. You always engage with an expert to resolve your issues quickly and efficiently.  

We've got the know-how to make every installation a success

We can’t think of any other Telco and IT providers in Australia that have the background and experience that we do to merge critical business infrastructure with the latest tech. This combination is very important, as it allows us to eliminate delays with carrier and installations, always ensure the correct products are chosen for the purpose, and resolve faults faster.

You’ll find a number of companies who claim they do Telco, but have adopted it as a side-arm of their business, and don’t have the deep knowledge of “how things are built” that make all our installations successful. Prosum are your one-stop-shop; a single company that can take responsibility for scoping, design, ordering, implementation, and post support, all within the one business.
