Hi Does Sangoma 8-port card A108 support PCIe version 2.0 ? The card is here http://www.sangoma.com/products/hardware_products/digital_voice_and_data_networking/a108.html And we want to use 3 such cards in this motherboard because it has 3 PCIe slots of version 2.0 http://www.intel.com/products/desktop/motherboards/DX58SO/DX58SO-overview.htm Is this a good idea ? Do you have any experience with multiple A108 with PCIe on the same motherboard that supports PCIe 2.0 ? Any comments will be helpful. Thanks, Anita Hall Simmortel Voice. -------------- next part -------------- An HTML attachment was scrubbed...

Thank you for your info Moises. For those who want to have a high density system, can you provide what modifications to the Dahdi (or anything else) do you make?

Those modifications are done via regular Sangoma installation with a special option to the Setup script. http://wiki.sangoma.com/wanpipe-linux-asterisk-appendix#zaptel_adjustable_chunk_sz http://www.sangoma.com/assets/docs/misc/2009_10_09_How_to_Reduce_Asterisk_System_Loads.pdf Moises Silva Senior Software Engineer Sangoma Technologies Inc. | NEW 100 Renfrew Drive, Suite 100, Markham ON L3R 9R6 Canada t. 1 905 474 1990 x128 | e. moy at sangoma.com On Sat, Sep 18, 2010 at 9:45 AM, Nyamul Hassan <mnhassan at usa.net> wrote:> Thank you for your info Moises.
