  • 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 transition our College to a Cloud IP Telephony platform successfully. 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.
