Cpu usage would be the bottleneck, most of it used by just handling the
audio packets over the network.

Asterisk 1.2 handles a DS3 of SIP-SIP forwarding easily for us on a

1% of CPU and 6% of RAM with 672 channels.
With RTP passing through, 200 channels on a typical P4/1GB solution
seems to be about the breaking point. [G.711, no transcoding]
What is the bottleneck at this point? CPU usage, interrupts, or bus
contention?
Can you post a few lines of "vmstat 1" and "vmstat 60"?
Also, what kernel and distro are you using in these installations?
