hi,<br>
<br>
any experienced user please guide us newbies to tune echo training intelligently.<br>
<br>
echocancel can have values of 32,64,128,256, and echotraining=400 or 800<br>
<br>
my test setup: SoftFone --- * --- PSTN<br>
<br>
from the default values of echocancel=128 and training=400, i observed
that if SoftFone is on the same LAN with * there is no problem with the
echo for me.<br>
<br>
but when SoftFone is on the internet then echo reappears.<br>
<br>
Questions: are there any rule of thumb like when the latency
increases, how do i supposed to set echocancel from default of 128? is
it higher 256? or go down lower to 64,32? the same question with
echotraining=400/800?<br>
<br>
thanks,<br>
<br>
