I'm experimenting with using SIP and softphones on our LAN (and eventually
WAN.)
I'm amazed at how variable the quality is even on a lightly-loaded LAN.
I have two test Windows 2000 machines connected to the same HP Procurve
4104GL switch (which is supposed to have QOS support enabled by default) at
100mbit with a softphone loaded on each.
Conversation is great until one of the machines does almost any kind of
network access. Then there is immediate "crunchiness" or skipping of audio.
I've tried a variety of softphones (eyeP media, SoftJoy SJPhone) and codecs
(G.729, G711ulaw) but all seem to have this problem.
Am I missing something with configuring QOS with Windows 2000 Professional
itself? I tried enabled 802.1p support on the NIC's but this didn't help
either.
