We are running FreeTDM on a very cheap Atcom card, which used another module ph_tor3_e1 on top of Dahdi. I believe this is derived from Torrenta. http://www.atcom.cn/downloads/TelephonyCard/drivers/AX-4ET/E1/ph_tor3_e1.c On Ubuntu 10.04 this gives problem as the module ph_tor3_e1 (and hence dahdi) does not unload. Sometimes the machine hangs and needs to be rebooted. This module has not been updated for the last 2 years during which the linux kernel has changed (I am told). Is there any other manufacturer of torrent card who would be using the same architecture and keeping his drivers updated ? If not, what steps do I need to take to update this driver to kernel version 2.6.32-37-server ? These are new waters and I feel so helpless :) regards, Anita
