Title: Port Specific QOS
Product review: We use the RVS 4000 exclusively for SIP and VOIP product installation. Setting QOS can be ineffective when users are streaming voice,skypeing, video conferencing and when every other link on the web is putting up commercials and streaming video and while webinars are getting more and more popular. Most of these packet types have similar QOS assignments. Using port specific QOS, we can prioritize bandwidth to allow our voip PCs priority over any other traffic. Plug our voip device into port one and give port one priority over all other ports and clipping, delay and jitter disappear. You have to upgrade firmware to get proper full cone NAT translation and address porting, but once done, this router works great! One more thing. Disable DOS or the router will block Voip providers, mistaking voice over IP data for a data flood from the voip provider's IP address.
