From our customers"We have found VoIPmonitor to be an essential tool for our customer VoIP troubleshooting. Before VoIPmonitor it would take a considerable amount of effort to pinpoint any problem be it call quality or NAT related issues. We have been using VoIPmonitor for a number of years and the product development is one of the best I have seen, personally I think VoIPmonitor GUI is a must have for all VoIP businesses." - Ashley Breeden, Managing Director, URL Networks
Q&A With Nolan Rollo on the Benefits of Using VoIPmonitor
"I just wanted to write to say that VoIPmonitor has been a HUGE help to us in managing our VOIP service in the face of South Africa's poor quality Internet environment. Aggregating the summary data provides fantastic information showing quality trends for individual customers, classes of customers and overall. The "clean" PCAP files are a huge help for debugging. What a pleasure to be able to go back in time and pull out a call from days ago and look at it packet by packet. So thanks so much for this very useful program!"
Steve Davies Technical Director Connection Telecom (Pty) Ltd
"Telephonic is proud to be a sponsor of the VoIPmonitor open-source sensor project. We are also very satisfied users of VoIPmonitor's commercial interface. Telephonic has had VoIPmonitor in production since early 2010. In addition to using VoIPmonitor to ensure call quality across our core network, Telephonic frequently deploys VoIPmonitor sensors at our clients' premises. The ability to monitor call quality not only within our core network, but also over the 'last mile' to the client, and then within a client's own LAN, has been a game changer for Telephonic. The end-to-end call quality awareness that VoIPmonitor provides, and VoIPmonitor's advanced troubleshooting tools, have been a major enhancement to Telephonic's operations."
Graham Nelson-Zutter, CTO & Co-founder, Telephonic Communications Inc.
