Sorry if I was being rude or arrogant.

Someone had mentioned to me that static IPs are best for VoIP so I went ahead and got some from Aquiss. It was a £12 setup charge so there's no point in throwing them out now really. Besides, I'd like to access the IP phones remotely if something does go wrong with them if I'm on holiday or something.

The latency issue still isn't fixed however I think that thread is dying out and there's not much I can do.

Is that Draytek good? Can you buy such a thing as a QOS attachment which hooks up to the modem and prioritizes all traffic in and out to it?

Thanks

The key is what VoIP handsets and which service are they using?

There are some voip systems that behave fine behind NAT, and some that may not, or get confused when multiple handsets are present.

They are Cisco SPA942 phones and are using an internet VoIP service called Gradwell.

In reply to a post by MrSaffron:

You need a router that will do NON-NAT and NAT simultaneously

That was where I was stopping and thinking...how to get one static IP address to be a NAT'ed address. In the end, I was coming back to using NAT and forgetting the static IPs.

One alternative could be to get a second router and setup a static route between them, using the existing router as a DHCP server for the non-static requirements (with NAT enabled, firewall happiness etc).

That way, you can even choose the new router specifically for staic routing and having a solid firewall onboard, or at least well-setup filtering.

If I was doing this at home (and when I've done this at festivals too) what I've done is one device handling the ADSL termination and NON-NAT, then a seperate cable/DSL router providing NAT services on one IP. With any other services needing a public IP connected to the external router.

Keeps PC's away from other things etc

Static IP's are nice and easy, BUT a static IP IS NOT A PUBLIC IP. I think someone may have suggested something, and you went a step further.

The 2820 supports QoS, and can even take two phone handsets and make them into voip handsets.

Yes.

Altenatively, the 5th IP could be assigned to an old PC, setup as a DHCP server, with lots of security and filtering. I'd suggest Linux, but not sure if the OP wants that.

I wish things would just work

I haven't got room to put an old PC in (if you can see where the modem is on the old thread) however I do have another router I can use.

I want a really good advanced QoS feature but is there any for a low price? I don't even know why I bought static IPs as I don't even know how to work them. Just keeps coming up 'Checking DNS' on the IP phone now whenever I typed in the external DNS.

Looking at that handset, I see lots of posts about port forwarding, so with multiple phones on the same NAT router, it might be better to assign a public IP to them.

VoIP is not my speciallity, but if the poster is of limited technical ability a managed service from people like http://www.gradwell.com/phoneservices may be worth considering.

http://www.gradwell.com/support/kb/article.php?id=245 is worth a read as covers port forwarding and multiple phones, see the bit about which shows that NAT is perfectly fine - just a little time spent configuring and assigning STATIC not public IP addresses.

Configuring multiple phones in one private network

You actually bought a block of Public IP's.

Unplug that phone and give a computer the exact same setup IP wise (make sure its software firewall is on) if the config is correct you should be able to see the internet.
