[Freeswitch-users] How to inspect the jitterbuffer?

Hi all,

I have a setup with a FreeTDM/wanpipe trunk and most of the time
the audio skips on the path to this trunk (e.g. after a period
of silence, RTP marker bit set by the sender). It is not an issue
with FreeTDM/wanpipe but more the way the RTP input is handled by
FreeSWITCH. My theory is the audio skips because the RTP 'queue'
has an under-run (while it shouldn't, there is no packet loss).

So how can I see if the jitterbuffer is enabled for a given call
(or globally)? Can I somehow see under-runs? The recovered clock/
clock skew? I couldn't find any of this in the wiki[1].
