I have everything working with oslec now. I had to drop back to dahdi 2.3.0.1 (I was at 2.5.0.2), and the best instructions were here: http://www.bsmdev.com/Reference/Tech_20100001.html There was two issues with the instructions. When I rebuilt dahdi and started up, I got two error messages: Unrecognized garbage 'Reserved' in WCTDM/0/2 ... and Running dahdi_cfg: DAHDI_ATTACH_ECHOCAN failed on channel 1: Invalid argument (22) [FAILED] The first warning message was resolved by copying the newer version of /usr/local/share/perl5/Dahdi/Chans.pm from the 2.5.0.3 source. It wasn't serious, but it was ugly. I don't have daughter cards on on all the slots on the TDM800 card, and it /whines/ about it. The second hard error was fixed by adding "dahdi_echocan_oslec" in front of the configured "wctdm24xxp" in /etc/dahdi/modules. Basically, the error message occurs because it does not know how to autoload oslec. It would be nice to find an updated version of the instructions that work with the very latest 2.6.* dahdi, but perhaps that should wait until the "echo" code gets out of staging and into the main kernel, in which case the dahdi code won't need patching. If there are any decent kernel hackers reading this, they might take care of the pending issues on that code and work with Greg K-H to accept it. In any case, oslec is very nice ( imagine the French soldier from "Monty Python and the Holy Grail" rasping "vehhuh naahs") Thanks again for the help. I hope this message finds its way to other struggling oslec users.
