What Our Clients Say about us

  • We needed an experienced ICT 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.

  • 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.

  • 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 provider we can rely on to provide and maintain our telephony and contact centre environment.

  • We recently selected PROSUM to supply, install and support a NEC SV9100 IP Telephony platform for our new medical centre precinct. The team at PROSUM were very professional throughout the installation process and have been a pleasure to deal with.
