SIP registration tracking is more of an issue with proxy they register with. Registrations are only a couple of packets per phone per 2-3 minutes. > I'm amazed at how many devices, even expensive high-end ones, can not do > UDP NAT properly. This is usually a settings thing, and you can mostly get round it by increasing the UDP connection tracking times or by lowering the re-register times, usually setting it below 60 seconds is enough. > This device should handle an office of up to 15 people with both > computers and phones. You can often trade off tcp connection tracking times and increase UDP no problem at all. > Other than that we do not require any special features though QOS > support would be nice bonus but not required. QoS is ok, but isn't "great" unless both ends support it properly. You could get a WRT54GL and then upload one of the 3rd party firmwards, not 100% off the shelf so would probably fail your requirements, but they can be one of the most powerful off the shelf devices you can get your hands on, and they are below 100$. There are similar devices to the WRT54GLs that have faster CPUs, USB ports for mass storage etc. Maybe the ASUS variant off the shelf might do, although I haven't used them so no idea how configurable/useful they are.
