Thanks alot, Ray Well, looking at cat /proc/meminfo, I am getting like 250M memory cached, with 512M total RAM, for all the gateways I have, this is quite consistent. Total Memory usages are always low after reboot and then go up to 450M with time. I was informed that this is normal for Linux.
Thanks for your input on Managed switch. However as said, I tried both Managed switch and non-Managed switch but have reaped the same result with packet loss when there are more active calls. Do you have any experience whether I need a good PCI LAN card like 3COM or Intel Express due to the demanding VOIP packets or do you think Intel ONBOARD LAN card should be sufficient?

Switches are will known not to auto-negotiate properly. All switches, nics, routers, etc should be manually configured for full-duplex. Make sure each connection is set appropriately for 1000/100/10 mpbs, what ever is appropriate for that connection. And yes, you can get full duplex for 10 mpbs connections (in answer to a message a while back on the list). Managed switches are best becuase you can look at them and get an idea of link/packet errors on each port. Obviously you want to completely eliminate errors on each port. Once you've done that, you should be well on your way to a reliable, scalable solution. Quoting "T. Chan" <[EMAIL PROTECTED]>: > Dear All, > > Just an experience to run by all you experts out there.
