I'm interested in one thing: as I know asterisk retranslates the media
stream with the next way
1. Gets the frame with the UA1's codec
2. Retranslates it to slan
3. Ratranslates slan to UA2's codec
4. Send the frame
Correct
It seems to me, that it follows these steps anyway, the question is:
Will Asterisk retranslate the frame ua1->slin->au2, if the codecs of the
1-st user and the 2-nd are the same? I need him do not touch the frames,
just retransmit them as is.
In general, this is not necessary. However, there are some cases where
the frames still have to be translated into slin. For example, if
someone is listening to the call using ChanSpy, the audio in both
directions must be translated to slin so that it can be mixed and then
sent to the person listening.
