Read What Our Clients Say about us

  • 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 conducted a review for potential VOIP providers that could implement a reliable and feature rich cloud based IP Telephony platform. After reviewing other providers, we selected PROSUM who was able to successfully transition our College to a Cloud IP Telephony platform. PROSUM’s expertise is of the highest standard and I have no issues in recommending their solutions and services. Staff are particularly impressed with the high quality audio afforded by the HD handsets and due to the outstanding clarity, wonder if the other party is still there as there is no ‘pops’ or ‘clicks’ on the line.

  • 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.
