Then my idea is not your solution, nor is echosquelch, I guess.  Yes, it
would be possible to kludge chan_capi to alleviate your problem; no, I
do not think it would be the right solution.  If the far end hears echo,
it's coming from the near end, that is from your softphone.  You could
try to use something else to confirm that (a hardphone?).  I suggest
that you play with the mixer settings on your own machine, because it's
your sound card that's recording the far end's voice!

Bye,
