If you are using Ekiga from http://www.ekiga.org, go in file
src/endpoints/pcss.cpp, and look for the class GMSignalFilter and for
function AddFilter. You can use a similar class, or use that one
actually, to modify the buffers :
- before playing audio in the speakers (ie after reception and decoding)
- before sending audio on the network (ie before encoding and
transmission)

No.

It should work as soon as you transmit video. So I guess you are not
transmitting video at all.

No, not yet.

The record of conversations, yes. The rest is perhaps of little interest
for most users. I will send you privately a patch I have received a
while ago that allows conversation recording. You will have to rework it
to adapt it to Ekiga, but it will be a basis.
