Answering myself, it seems I was incorrect, as jbenable is enough to
activate the buffers. I see the options different meanings now. Sorry about
the buzz.. :)

The statement about using jb-settings in peer definitions does however seem
not to be true. I tried adding the settings to a friend definition and it
did not activate a jitter buffer for that friend. I added these settings:


and when placing a call from the friend, I experienced no delay, which I did
when having activated the settings in the general context. The lack of delay
would indicate no active jitter buffer. Have I missed something?
