The timing issue which is theoretically only needed when using a hardware 
interface or conferencing and MOH from what I understand.
Bottom line is the ztdummy hack when not using hardware (I don't know of it 
will passthrough reliably) yields less then reliable results in xen.

I tried many vanilla centos installs on different xen 3.2.0 setups that all 
produced an asterisk server that missed/dropped calls or just plain was not 
consistent.

Moving the asterisk setup into a non virtualized environment produced more than 
one server with duplicate configs that all worked perfectly and have never 
missed a beat yet.
