Client Testimonials
What our clients say about us
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.
Andrew Trinh,
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.
Therese Chakour-West,
INFORMATION TECHNOLOGY MANAGER - STIHL
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.
