The problem is that the ztdummy driver assumes 1000HZ, and a 2.6 kernel
under xen . I worked around it by making the ztdummy driver count 10
ticks for each jiffy. My music on hold works now but clicks and pops a
bit which I think may be because of my kludge.

Thanks

Do you mean it has a hardcoded value instead of using the "HZ" macro???  I'd 
consider that a bug - have you tried contacting the codes maintainers?

Good to know it's working.  Just *please* don't use Green Sleeves or anything 
by Vivaldi!  (I've spent too much time in telephone queuing systems this year 
- it's made me a bit sensitive to hold music ;-)

Cheers,

Being subscribed to both lists, I thought I'd funnel this through to the 
asterisk-dev list as possibly informative. (Note that you must be 
subscribed to the asterisk-dev list to post there.)
