I have a draytek which can do QoS, it can do outbound fine but struggles with incoming data understandably, a http download can cause breakup in voice on the VoIP phones, is there any way around this other than going with an ISP that offers QoS their end?
VoIP QoS

It probably won't work on a draytek but a firmware with inbound qos (tomato) can do it, although since it's not "true" qos you need to set the inbound lower than you would with a qos system. In my case its 600k to prevent games/voip (~120k) breaking up, but it sill adds 4-5ms which is a fair trade imo.
A qos isp would be preferable, if you find any of those though...

Which routers use Tomato? I've tried everything with the Draytek so I'm going to have to bite the bullet and buy a new router...
What sort of bandwidth reservation do you have set for the VoIP QoS class? You might need to set that a bit higher for it to stop HTTP breaking it up, also if it's something like a 2820 router, it's worth checking the QoS statistics while using the connection to check whether or not the traffic is being detected as part of the class or not.
Strictly speaking outbound qos is all you need, the problem is you almost always have more upload than you need to download so it's not very useful. Personally I'd call draytek before getting a replacement, they're support is switched on in a way that most aren't i.e. it's actually worth talking to them.
As for tomato, well there's talk of a new kernel but currently there's no n or gigabit support soy uor limited to older hardware. If you want either of those you need to put the tomato router between you modem and a gigabit switch/access point. The wrt54gl is the more easily available compatible router, the basic version of tomato should be more than adequate on it.
Just put your router mac into the highest category and ensure it's been assigned adequate bandwidth but be aware, the inbound qos works by rejecting packets after they've been sent so you loose some bandwidth, it's the trade-off for uninterrupted voip/games. This is the best place to find more information on it.

To add, you likely won't find an ISP offering QOS in the UK. BT's xDSL platform doesn't support DSCP or COS so basically that's out. Virgin media don't offer a product I know of, so you're left with whether any of the LLU providers offer a QOS enabled service - as they don't really serve the business market I find it unlikely...
And we don't have LLU...

On the plus side 21CN has limited support for QOS, though it's attached to a fairly baffling pricing policy as I remember (from BT wholesale to your ISP) and falls short of the QOS featureset which has been available on 'proper' circuits for years. Oh well, it's a start at least...and it should allow your ISP to provide you VOIP reliably at least (why you'd want it is open to question though when you've got a phone line to have the broadband delivered over anyway...)
Because you can have multiple lines without multiple line rentals.

Yeah, if you have some specialist requirement I guess...I was speaking more generally...
