From the Digium emails:
- I'd use two machines, with two quad cards each. And then, I'd need to be using only the G.711 ulaw protocol. Then, I'd still use a mid-range dual Xeon CPU machine in the 2.4GHz+ spectrum.
We do not want to be limited to the G.711 ulaw codec and we would need at least four quad-span cards for a single machine setup. Any single machine setup also has inherent scalability issues.

Originally, we planned to implement this design by purchasing one multi-processor machine and putting multiple quad-span T1 cards (Wildcard TE4xxPs) into it. Through research, it was determined that the PCI bus couldn't handle the digital signal processing (DSP) from more than one quad-span card.
The PCI bus doesn't do any processing.. The CPU would be... you can get two or more quad cards in a box if you don't do any transcoding.
