Ever since our switch to VoIP, I've been pulling my hair out. Call quality has been a huge issue. I've spent hours and hours troubleshooting this issue we're having.
What I've done so far...
...Called ATT, had them come out to our office and check our equipment (modem/router combo). The reason for this was when I would do speed tests, I would get speeds all over the board, we're supposed to be getting 6mb down, and 768kb up (I know you never actually get those speeds but still.) Anyhow, they tested everything and said it was ok, and they did notice the speed drops, but only when they connected our local network. When he tested without our network, it gave him great constant speeds, but when he connected our network he saw the issues.
...I've made sure no one is streaming music/video, or uploading files.
...I've checked each computer for viruses.
...I've configured the phone server to use audio codecs that use less packets/bandwidth
...I've even called att and added more bandwidth
So point is, I need a tool that I can load on one computer and monitor the bandwidth being used by each computer on my network. I've googled it but can't seem to find a tool that does this. There's got to be a tool for this, or am I crazy and pretending that itís too easy?
Our network is pretty small, 30 devices, including VoIP phones, give or take 1 or 2 (depending on laptops/phones connected to Wi-Fi)
Any help would be GREATLY appreciated, I'm going insane trying to figure this out!
