Not sure, but I would have thought a Fritzbox was able to play the role
of a SIP outbound proxy.

A timeout is different from a 404.

Please post a -d 4 output somewhere (pastebin.ca) so that we can analyze
what the problem is.

It is most likely due to a problem with the ALSA libraries.
Try to see on both sides if :
arecord -D plughw:0,0 -c 1 -r 8000 -f S16_LE - | aplay -D plughw:0,0 -c
1 -r 8000 -f S16_LE -


arecord -D plughw:0,0 -c 1 -r 16000 -f S16_LE - | aplay -D plughw:0,0 -c
1 -r 8000 -f S16_LE -

Work as expected.

If you are using the "Default" device in Ekiga, please try -D default
instead of -D plughw:0,0
