--- Results after 20 passes --- Best: 99.987793 -- Worst: 99.975586 -- Average: 99.986572
The only reason I'm looking into this is because my users are saying that the quality of the calls with the previous PBX was better and clearer. With *, they hear everything fine, but, every once in a while there is like air gaps or white noise that last for fractions of a second. Am I looking in the right place?

Rich, did you check IRQ's? Our zttest results didn't improve markedly
when we did either change (IRQ's or H/T), but the problem went away
regardless.
Other than that Digium have recommended throwing out our SCSI320 RAID hardware and replacing it with IDE (i.e. not SATA) kit, although thankfully we haven't had to make this retarded change (yet).
I would also recommend trying to disable H/T in the BIOS (rather than via software) as I wonder if H/T still runs on your box (but is not accessed by the OS), so may still be causing you grief.
Yes, been through the majority of items including irq's, swapped motherboards, ide only, nothing else running, command line only (no frame buffers), upgrade from rhv9 to fedora 3, mucked with pci latency, etc. Had not tried the hyperthread thing until now, but that had no effect either. Even upgraded the TDM card to the latest rev h.
Still think its either a bad TDM card design, or, TDM driver issue as to why we can't approach zttest results of 100%.
I'm hoping that Steve Underwood's utility to measure the TDM results helps to identify the root cause.
