More tha one TC400BLF?

Hi all,

Does anyone tried before to use more than one TC400BLF DSP for asterisk?

The case is one asterisk server witch is in nat=yes mode and g729 passthrough.
With this setup i get from an Intel XEON 2.8, 80 calls simultaneously or 160 channels. I want to rich the 240 calls or 480 channels. If i can use 3 TC400BLF in the same server hardware i can achive that.
I’m asking this because i was reading in other forums that more than one Digium PRI pci cards are not performing well in the same server hardware.
so I’m wondering if is the same case and for TC400BLF ??

Thanks in advance for any help.
