Not that I've got any reccomendations as my router is an old p200 and I
don't use voip, but just because you can do an ftp upload + voip OK it
doesn't mean that QOS is not required for others.
The delay from one ftp upload will be limited by the tcp (c)window
advertised by the remote end and/or the size of the buffer in your
modem/router.
Try P2P (multiple tcps) or different kit and your results may be very
different - mine and many, AIUI, modems have buffers that are > 2
seconds at 288kbit upstream dsl rates.
