How do I troubleshoot voice quality problems on a MultiVOIP network?
Start troubleshooting by analyzing what software packages utilize the connection for sending data. Look for processes that occur during business hours that could be scheduled for after hours. Investigate the bandwidth being utilized on the connections to determine if you are over-driving the circuit. Your routers, along with the VOIPs, can give clues to packets being lost, and other network traffic statistics. Set up your routers to support DiffServ, or IP Precedence. This will allow the voice packets to have higher priority than data, when your bandwidth is being utilized heavily.
