Thanks Atis

I'll give that a shot and see where I end up.

NoCDR wouldn't cause that, as that's supposed to skip posting current
CDR. Next entry would be caused by either ResetCDR(w) or some
application that creates new channel (i.e. Dial or Queue). You can
enable "full" log and set verbosity and debug to higher values, to see
all what's going on.

I'm not sure about value of ${CDR(UNIQUEID)}, but you can use just
${UNIQUEID}. If you want to pass variable to child channels, you
should make it inheritable. I'm using:
Set(__call_id=${UNIQUEID})
