Excellent, I will stick both sets of configs in the appropriate files.

Yup, it took me a while to get everything right in the rpm spec file but
it seems to work ok now so the hard part is done.

Those are the same ones I use too. They work quite well.

I am subscribed to that list too. The sheer number of posts is a bit
overwhelming these days although I enjoyed reading the threads about
your 512 simultaneous call system and the ramdisk/tmpfs discussion. If
you are still looking to test the various ztdummy incarnations (plain
ztdummy, ztdummy-pll and ztdummy-rtc), this weekend I'll have updated
(s)rpms at http://www.laimbock.com/asterisk/ that will have all three.

Thank you for your elaborate answer.

Patrick
