Tks Leif and Ian, aren't these TWO separate issues:
===international calls may well have more jitter, and we have to put up with it ===As for lo-quality timing on a virtual machine, I seem to have read somewhere in my research that some software (was it ztdummy?) can replace proper hardware timing? And even then timing was only an issue for music-on-hold and a couple of things?
