Windows XP Home: QoS per application

Hello Experts,
I'd like to install some softphone in my client's computers, but I'd like to find out (if exists) a way to prioritize traffic from this specific application going out/in their windows machine ... They basically use Windows XP Home.
I've read that Vista comes with this feature but I would love to do this with XP too ...

Don't worry about the QoS outside his computer ... What concerns me is the absence of control on their connection.

Thanks,

XP supports QOS but it is up to the specific software application to use the feature.
See http://support.microsoft.com/kb/316666

Hi grblades,
Thanks for your response ...
But what I was looking for (if exists) is a solution that would priotize traffic from a generic application that does NOT use the Windows QoS API, because I think this softphone doesn't yet (SJPhone).

Please tell me if you know any,

Thanks again,

Maybe I don't understand your question, but whatever you are using to access the internet should have QoS settings.  Your switch, router, etc.

Actually, the routers, access points, switches are already configured ...
But my problem is that my customers access my network wirelessly through bandwidth controlled access points ... I just need to protect their voice calls from themselves, clogging up their connection with P2P and others ... after the packet is out their network interface ... I'll take care of it ...

Thanks

unfortunately, there's no generic QoS support. WinXP QoS scheduling has to be used by the app to prioritize, otherwise the computer will consider that application as just normal data traffic and not mark or priotitize accordingly. If you attempt to force the markings at the switchport feeding that laptop you essentially prioritize all traffic from that machine which defeates the purpose. Essentially you need a soft client that can support QoS marking.

the other way you can try to do it, depending on the network hardware you have, is to setup ACL's that will mark traffic on specific signalling TCP/UDP ports and prioritize those rather than prioritze with the DSCP or whatever markings you're using.

you might also trying using a smaller codec like g.729 which can help with quality on lower bandwidth links

Thanks,
I found one ... X-Lite now supports it ...

Hi. I use Eyebeam (the licenced version of X-lite) which is basically the same as X-Lite but with an extra few lines. We use bluetooth headsets connected via USB bluetooth dongles and this solution works very well until you try moving large files too and from your machine over the network. Looking at your question, I seems that you have managed to configure X-Lite with QoS so that the voice packets are given priority over data. If this is correct, I would be really grateful if you could let me know how you went about doing this.

Much appreciated.

Try using a headset to see if you have the same problem.
Your problem could be QOS in which case you will have to upgrade to professional wireless access points with built in QOS support.
Or it could be the fact that wireness b/g operates on the same frequencies as bluetooth and is interfering with the headset. Hence why I suggest trying a wired headset. I get similar interferance with my wireless mouse and copying large files.
