I'm having some echo issues on a couple of lines and I'm pretty sure it's a question of tuning the card or picking echo cancellers, I would just like some thoughts from someone who's done it sucessfully. I've fiddled with the echo training stuff and can't seem to get rid of the echo. I've tried adjusting the gain to a happy level, but I'm still left with the client side (not the callers) hearing echo. I've read about this 1004hz 0db test number, but haven't been able to track one down for Bell. The lines are really long (too long for DSL, so over 7km at least) and in the country, so they're probably not that great, and that could have something to do with it. Either that or the echo canceller that I've picked (whatever the default in the source is) isn't working for me.
Has anyone used this hardware with analog lines with sucess? Any tips/tricks you can provide would be awesome. I ran the fxotune program, but I really don't understand what it acutally does, it seems to have had no effect and each line in /etc/fxotune.conf is exactly the same... #=8,0,0,0,0,0,0,0,0 - Ian
