"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."
