Not me, at least not in this instance. The self-described doofus here is a contributor to Reddit’s section devoted to networking, who says he acquired his doofus bona fides while troubleshooting his company’s VoIP system. Mr. Doofus explains:
I’ve been struggling with nasty packet drops occurring on VoIP calls at our data center for a few weeks now and for the life of me I couldn’t find the source of the issue. I thought at first that the servers I have running our custom VoIP applications were just overloaded, but the issue would show up on just a single active call. Restarting the VoIP servers didn’t help, all of the QoS markings and switch/router prioritization were spot on, the ISP was returning a clean bill of health on the circuit, etc., nothing was making sense. I made a few internal VoIP calls that stayed on the LAN which were crystal clear, and made some calls that also traverse the router to another internal subnet which were also clear, so I now knew the ISP connection was where the trouble was beginning.
