I've figured this one out myself, with a much better result that I expected.
I upgraded the router to the latest firmware at wl500g.info and set the MTU from 1500 down to 576. The Billion 7402VGP was prioritising the packets, but the packets from the wl500g were too large, and held up the VoIP packets for too long, given the connection only has a 256Kbps upload. It's now working fine and the small loss in efficiency from the lower MTU is more than balanced by being able to use all of the bandwidth that the VoIP isn't using.

I need a way to limit bandwidth to prevent my servers from ruining VoIP calls. I have a box running CentOS 4.4 that will be hosting a few CentOS 3.7 VMware images. The box is connected via an Asus wl500g router, running default firmware. The wl500g makes its own PPPoE connection through a Billion 7402VGP running in "PPPoE with Pass-through" mode. VoIP runs OK next to downloads, but if I'm uploading it can cause the phonecall to break up or disconnect. I figure I have three options: * use the router, which will require a new firmware that supports bandwidth limiting - probably openwrt or something at wl500g.info I haven't used either firmware and I don't know if that's an option * limit bandwidth from each VMware image of CentOS 3.7, using something in CentOS 3.7 * setup a virtual LAN for the VMware images and then limit bandwidth using CentOS 4.4 * reconfigure my network to run my servers from the Billion 7404VGP (I'd really prefer not to, but as a last resort it should work). Any suggestions on a preferrable method, or any How-Tos for a method would be appreciated. Ben
