Hello there again, : > I recommend the Sangoma WAN cards. I've been using them for at least 3 : > years under linux, and they are well supported by Sangoma and the linux : > community (you'll see the driver in the distribution). : : Regarding Sangoma solution, what Linux kernel version they are : supported on ? I would need 2.4.20 or there about. Perhaps I wasn't as clear as I could have been. Support for their cards has been a part of the linux kernel distribution for quite some time. $ find linux-2.4.20/ -type f -name wan\* -print linux-2.4.20/include/linux/wanrouter.h linux-2.4.20/include/linux/wanpipe.h linux-2.4.20/include/linux/modules/wanmain.stamp linux-2.4.20/include/linux/modules/wanmain.ver linux-2.4.20/include/config/wan.h linux-2.4.20/net/wanrouter/wanmain.c linux-2.4.20/net/wanrouter/wanproc.c linux-2.4.20/net/wanrouter/wanproc.o linux-2.4.20/net/wanrouter/wanmain.o linux-2.4.20/net/wanrouter/wanrouter.o linux-2.4.20/drivers/net/wan/wanpipe_multppp.c linux-2.4.20/drivers/net/wan/wan.o linux-2.4.20/drivers/net/wan/wanpipe_multppp.o linux-2.4.20/drivers/net/wan/wanpipe.o linux-2.4.20/Documentation/networking/wan-router.txt linux-2.4.20/Documentation/networking/wanpipe.txt linux-2.4.20/Documentation/DocBook/wanbook.tmpl Tschüs, -Martin -- Martin A.
