a1200 with bad sound quality

I can not get oslec to stop, if i stop it, and restart zaptel, oslec is still running. How can I turn it off - or do you mean yum remove oslec?

or do you mean echocancel=no in the channel in zapata.conf?

set echocancel=no in zapata.conf

otherwise have to re-compile zaptel.

Ok. I also want to set my rxgain a little higher because some calls have low volume to the internal extension, but I think this will cause echo to come out more - is there anything I can do to work with that.

With OSLEC, you can use much bigger volume w/o problem.

i turned off all oslec, but the echo on the calls was very bad, and that was with standard rx/txgains. I turned the oslec back on and calls sound clear, but the random scratchy calls still seem to be an issue which seems to happen on multiple trunks.
