What Our Clients Say
Very good and prompt service. Friendly staff.
Paul Bhatti,
WATSONIA VETERINARY CLINIC
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.

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.

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!

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.
