I switch the wires in lines 5-8 (i.e. reversed tip and ring) and reran fxotune to tune the lines. fxotune.conf ended up looking exactly the same as before the change. Since I was expecting/hopping to see a change but did not I switched everything back to the way it was. Is there a way to test the lines, using a multi-meter maybe, to tell if the tip and ring are correct or reversed?
After putting things back I reran fxotune to get the verbose output. It, foxtune.out.gz, is attached. fxotune seems to have had a better time with line 7 during this run. fxotune.conf now contains: 5=7,255,251,251,2,255,255,1,255 6=7,255,251,251,2,255,255,1,255 7=4,0,0,0,0,0,0,0,0 8=7,255,251,251,2,255,255,1,255 9=4,0,0,0,0,0,0,0,0 10=5,0,0,0,0,0,0,0,0 11=0,0,0,0,0,0,0,0,0 12=0,0,0,0,0,0,0,0,0 I tried calling directly into the lines above and it seems lines 5,6,8 have much more echo than lines 7,9,10. So just for fun I edited fxotune.conf to the following and reloaded (fxotune -s) it: 5=5,0,0,0,0,0,0,0,0 6=5,0,0,0,0,0,0,0,0 7=4,0,0,0,0,0,0,0,0 8=5,0,0,0,0,0,0,0,0 9=4,0,0,0,0,0,0,0,0 10=5,0,0,0,0,0,0,0,0 11=0,0,0,0,0,0,0,0,0 12=0,0,0,0,0,0,0,0,0 Unless I am just spacing out the echo on 5,6,8 seems less now. I really have no idea what is going on. John On Fri, Jun 6, 2008 at 1:31 PM, Matthew Fredrickson <[EMAIL PROTECTED]> wrote: > John Morey wrote: > > Tilghman, > > > > Thanks for the pointer.
