Running Asterisk 1.6.2.9, DAHDI 2.3.0.1, CentOS 5.5 (update to date as of a week ago), I've installed a Digium AEX800P with 2 X400M FXO Modules and 1 VPMADT032 Module, hooked up to 5 analog lines. I get the error message referenced in the subject in my dmesg output everytime I load / reload DAHDI using the command "system dahdi start/restart". When I make an outbound call over these analog lines, I'm told in the CLI " WARNING[22601]: chan_dahdi.c:2685 dahdi_enable_ec: Unable to enable echo cancellation on channel 5 (No such device)", and there is noticeable echo on the line, hearable by the caller inside the office, not by the recipient outside the office. When I make an inbound call, I get the same message, with echo still heard by the person inside the office, and not outside. I've run fxotune -i 4 -e 5 also, and still receive the same output.<br>
<br>Below is my chan_dahdi.conf, my system.conf, my dmesg output while loading dahdi, if you need anything else let me know:<br><br>*** chan_dahdi.conf ***<br>[trunkgroups]<br><br>[channels]<br>usecallerid = yes<br>hidecallerid = no<br>
