However after the system has been running awhile(overnight) voice quality drops dramtically. zttest at that point usually reveals seemingly random worst measurements at around 97.XXXXXX%. --- Results after 224 passes --- Best: 99.987793 -- Worst: 97.692871 -- Average: 99.881243 After a reboot, I get results like the following. --- Results after 70 passes --- Best: 99.987793 -- Worst: 99.975586 -- Average: 99.987444 during which the voice quality is excellent for a time. During the bad voice quality periods, the brunt of the poor quality is on the remote user end who hears loud clicks among other things. Internal phones(all sip) may hear occasional, brief dead air which I assume is during the clicks. This is my first phone system endeavour so I'm not quite sure how to resolve this. Some information seems to point at IRQ misses as the cause so I insured the card is on it's own IRQ and disabled apic however the symptoms still remain.
