Oh ... the 15% bit, that was me generalising, the help screens for the WRT recommend

Uplink:
Set this to 80%-95% (max) of your total upload limit.
Downlink:
Set this to 80%-100% (max) of your total download limit.

And I'd found a US based blog entry with a reply that appeared to be a Cisco employee that made a similar statement for the SPA, I didn't save the URL though, it will take me a bit of googling to track that one down again, will try.

I send faxes via my SPA2102 probably 10 or more times per week. Most of these faxes are to one Auckland number via a Telecom line and they always work perfectly. Occasionally, I send faxes to other numbers within NZ and these are usually OK as well, just the odd time I have to resend one.

I managed to get about a 90% success rate in faxing, in my early testing. Work has a really fussy fax machine, which is great for testing with.

Faxing wasn’t a requirement then however, but things changed, and as don’t have a PSTN line from Telecom, I ended up with another VoIP line from my ISP (Airnet). From discussions with them they utilise T.38, this has proven to be rock solid, when with a fully utilised link...

I've been doing some Googling as well and found this page:

http://www.dd-wrt.com/wiki/index.php/Quality_of_Service

The 85% / 15% rule is mentioned quite explicitly there and they also say that the HTB Packet Scheduler is the best one to use.

This has been a bit of an eye-opener for me on a wet/gloomy Sunday learning about third party firmware for the WRT54G. It's a pity you cannot use DD-WRT on the WRTP54G or it would be an excellent all-in-one option for VFX and Wireless-connected households such as you and I both have. However, there's something to be said for having separate ATA and Router devices, such as when lightning zapped out my router recently.

The DD-WRT web site is such a rich source of information on QoS and related topics. They even have a Bandwidth Graphing package available as an add-on.

I wish I had known about all of this before buying my ZyXEL P335U. It has most of the same QoS functions as DD-WRT, but getting information on how to use them is extremely difficult. I've had to feel my way by trial-and-error whereas there seems to be an active community supporting DD-WRT rather than a single manufacturer with overloaded Tech. Support staff.

Definitely something to keep in mind for the future, and if lightning zaps out my ZyXEL P335U, I will look at replacing it with a WRT54G flashed with DD-WRT.

Agreed. That's how I get around it too. I have a couple of Planet VoIP gateways that support T.38. It lets me connect my fax machine at home back to our Auckland office which still has a Telecom line. So I can send International Faxes via that line.

Back again, been watching a Jackie Chan movie with my younger boy and he's just decided to go and ride his bike through the lake forming in the paddock outside the house, so I've got a few minutes on the network again.

That wiki is excellent.

Good to know I'm not a complete idiot out here on my own without Nanny Telecom minding my bits.

... a large part of the paddock just walked in with Nick attached, gotta go and scrape him down.
