Good time of the day, Camaleón.

Thank You for Your time and answer.

May other OS components cause this? Though I do not know what. :o)

I have searched Debian on soft phones and found 

ihu (would call sip for me)

linphone - fails to run w/

ALSA lib conf.c:4687:(snd_config_expand) Unknown parameters 0
ALSA lib control.c:951:(snd_ctl_open_noupdate) Invalid CTL default:0


sflphone - calls but I do not here sound though all volumes on ALSA
mixer were high.

And I saw no more soft phones in Debian from repo.s.

So far, ekiga is the best option for me, and I would say, most
comfortable its GUI comparing w/ the above.

But was is bad to me w/ ekiga is - its doc.s do not specify my problem
- as what is expected to not work and therefore a fix is offered -
  works for me and therefore the fix works not for me - though the
  problem is listed by those fix makers but diagnostic is
  applicable for me and so their solution.

Thus, both modes - mono and stereo, 8/16 kHz work w/ my SB:

$ arecord -D plughw:0,0 -c 1 -r 16000 -f S16_LE - | aplay -D plughw:0,0
-c 1 -r 16000 -f S16_LE -

BTW, as a workaround w/ latency for redirection of my voice (from mic.
to speakers) :o) Not what I wanted, but better than nothing.

But ekiga does not echos my voice though as I have mentioned in other
messages - mic. volume reflects my speech.

Sometimes, for singing is good. :o)

Thank You for link but sends me google start page.

OK. Thank You. I just would not install software from non-debian
repo.s. In case I will move it to a VM, then I will try it, though do
not know when.

That's what I think is bad in DEs: they develop their software only in
conjunction w/ whole DE instead of making working standing alone
functionality - like konsole or kate from KDE, ekiga, evince from
gnome, etc. Who prevents them from feeding command line parameters to
the GUI programs - at least?!

I will look for ekiga list - may they will shed some light on the problem.
