[Asterisk-Users] QoS General Question

2005-08-09 Thread Geoff Manning
How much of an impact can/does local network traffic have on call quality? Would opening large files on local servers affect call quality? We are running QoS on the router but that will only prioritize traffic in/out of the network. ___ Asterisk-Users ma

Half duplex by itself doesn't hurt (depends in number of calls and etc really, but anyway...) What is a killer for VOIP is duplex mismatch. If you have autonegotiation enabled, and your peer (the switch ?) has autoneg off, and 100/Full-duplex hard coded, you WILL have a duplex mismatch. And th
