QoS: If router supports QoS features, please enable them. QoS should be configured to prioritize traffic travelling to and from our VoIP server IP addresses. If the customer’s router supports bandwidth reservation, please reserve 80kbps per active phone call needed at the customer’s site. Typically, this will be done by restricting bandwidth usage for non-VoIP traffic. For example, here is how we would typically ask to have a router configured for 10 phones, using a 25mbps x 5mbps internet connection: • Mark traffic to and from both outbound proxies as “VoIP”. All other traffic is unmarked. You can also mark traffic based on the DSCP value of 46 or the DIFFSERV value of 184. All voice communications are tagged with these values for identification and priority queuing and routing. • Set maximum bandwidth utilization for upload and download for traffic marked VoIP at 2Mbps (this is really unnecessary, as the phones won’t use this much data). Give this data high priority. • Set maximum bandwidth utilization for upload to 4.2Mbps and download to 24.2Mbps for all unmarked traffic. (this will result in 800kb being set aside for upload and download for up to 10 VoIP conversations at 80kbps each). Give this data low priority. NOTE: FAILURE TO ADDRESS THIS SETTING MAY RESULT IN DEGRADED AUDIO QUALITY DURING PERIODS OF PEAK INTERNET BANDWIDTH USAGE. If you have any questions, or if you require any additional information to configure this customer’s network to support their new VoIP phone service, please contact our customer service department at 317-991-4300 or send an email to operations@hostmysip.com
