I've been trying out a voip phone, but it's laggy as hell on my 128/512 connection.

On my router I have the voip plugged in, my main host pc, and a remote desktop connection to a crappy guest pc which is used for browsing/downloading, anything net related.

Is it possible to easily stop the guest pc completely from accessing internet without breaking the remote connection between the host/guest? i.e. I can't disable the network adapter or unplug the network lead.

I find that if I unplug the guest, the voip lag is much less, but I don't wanna do that all the time. Even though the guest is not downloading or browsing, it seems to greatly increase the lag, so I guess it's taking some upload bandwidth even when it's sitting idle.

I know I need quicker internet but that's not an option at the moment.

Any ideas would be greatly appreciated.

Change the LAN settings on the guest system to use a proxy server with the home address (127.0.0.1), it's in the 'Connections' tab of 'Internet Options'.

Thanks, that works better.

You may also be able to set some QOS settings (=Quality Of Service) on your router -- Many routers have the ability to prioritize VOIP traffic that way.

enforcing a QOS for VOIP means that the router will give priority and dedicate all it can to your VOIP device, and have everything else fight over the remaining bandwidth.

I looked into QOS but my Netgear DG834 v2 is too old. Apparently the later versions support it, either native or with a hacked firmware, but not mine. While I was looking into QOS I did find out that my router does support DMZ, so I've set the VOIP box (Mitron MV1) a static IP address and set the same IP address as DMZ. I think that's correct, as the router is now always allocating my specified IP to the Mitron.

Anyway, the lag is down to about 0.5 secs now, down from roughly 2-3 seconds which was pretty much unusable. Next time I get a router I'll make sure it has QOS, but I have to work out a plan for that as it'll involve convincing the missus and she already let me lash out on a new gfx card a month ago:)

Thx for all the help.

just tell her the money you are saving vs land line/mobile calls
VOIP is going to cost the same if its down the road or the other side of the world

Funny you should say about the voip call costs. It's 15c per minute to call a local mobile, but only 2c per minute to call an overseas mobile. Still, it is about 50% cheaper than a normal phone.
