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?<br>
<br>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:<br><br> 5=7,255,251,251,2,255,255,1,255<br>
6=7,255,251,251,2,255,255,1,255<br> 7=4,0,0,0,0,0,0,0,0<br> 8=7,255,251,251,2,255,255,1,255<br> 9=4,0,0,0,0,0,0,0,0<br> 10=5,0,0,0,0,0,0,0,0<br> 11=0,0,0,0,0,0,0,0,0<br> 12=0,0,0,0,0,0,0,0,0<br><br>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:<br>
<br> 5=5,0,0,0,0,0,0,0,0<br>
6=5,0,0,0,0,0,0,0,0<br>
7=4,0,0,0,0,0,0,0,0<br>
8=5,0,0,0,0,0,0,0,0<br>
9=4,0,0,0,0,0,0,0,0<br>
10=5,0,0,0,0,0,0,0,0<br>
11=0,0,0,0,0,0,0,0,0<br>
12=0,0,0,0,0,0,0,0,0<br><br>Unless I am just spacing out the echo on 5,6,8 seems less now. I really have no idea what is going on. <br><br>John<br><br><br><div class="gmail_quote">On Fri, Jun 6, 2008 at 1:31 PM, Matthew Fredrickson <<a href="mailto:creslin@digium.com">creslin@digium.com</a>> wrote:<br>

</div>Also, I would like to see the output without the "-d" flag and with the<br>
"-v" flag. This will output a lot of data (the echo ratio for every<br>
possible coefficient setting it has tried per port).<br>
