I am using OSLEC on my home pbx.

I'm only using 2.6.17 and zaptel-1.4.4 at the moment.

Check the zconfig.h file in the zaptel source and make sure that the line: #define ECHO_CAN_OSLEC is not commented out but all the lines for the other echo cancelers are. Did you start with a clean source (or at least did a make clean) before you compiled? Are you using the zaptel-1.4.4.patch from the oslec SVN or some other patch? > If I look at what modules are installed: > > # lsmod > Module Size Used by > zttranscode 6280 0 > ztdummy 3432 0 > wcfxo 9760 0 > zaptel 200120 7 zttranscode,ztdummy,wcfxo > crc_ccitt 1792 1 zaptel Just for kicks, try inserting the oslec module by hand (insmod oslec) and see if that makes a difference. > In my kernel modules/misc directory I have: <snip> Hope that helps. -Dave _______________________________________________ --Bandwidth and Colocation Provided by http://www.api-digital.com-- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
