What our clients say about us

  • We recently had some issues with the installation of our PABX and the presence tools. Initial consultation with the manufacturer did not resolve the issue. We contacted a few third-party vendors and it was PROSUM who immediately identified the problem and resolved it in a timely manner. Since then, we have engaged PROSUM to upgrade our telephony infrastructure (which went without a hitch) and they are now installing our Wi-Fi network. PROSUM have the expertise and are very professional. I have no issues in recommending them.
