That's interesting one. Can you run zttest (or dahdi_test) and provide
some results as for accuracy?
From my experience (with Xen mainly) I was getting somewhere between 60-80 % accuracy which is really, really bad.

I don't have dadhi/zaptel running, since no hardware. Sorry, it's been a while, but seems I remember having had some issues with dahdi.
