No, it should always be there, I will investigate further. But your
tests seem to indicate that the problem is in Asterisk. I will try to
see if the audio becomes bad with time or if it is just the info in the
rtp packets that make the jitter increase when it should not. Asterisk
has no RTCP channel.
