Hi,
Please download dahdi source from the following link and recompile again. http://downloads.openvox.cn/pub/drivers/dahdi-linux-complete/releases/1.3.3/openvox_dahdi-linux-complete-2.5.0.1+2.5.0.1.tar.gz

Thank you. Re-compiling DAHDI from your source fixed the driver issue. Now I am having constant "Buffer re-sync occur from x to x" messages, Reading in the forum, it appears this is a compatibility issue with the motherboard. I read one solution was to set/reserve an irq for the slot/a800p but in Gigabytes wisdom they removed the option for reserving irq's for legacy boards from the bios. I will contact the manufacturer and see if there are any planned bios upgrades otherwise I'll use two 4 port boards (A400P work ok) or replace the motherboard. Thanks for your help. Motherboard model 970A-UD3.

Hi,
You can try another PCI slot. If the issue is still there also you can use A810, it's better than A800!
