Cross-posting because I didn't receive a reply from asterisk-bsd. System config: FreeBSD 6.2 Asterisk SVN-trunk-r76371M Zaptel svn 130 Sangoma a101 kldstat Id Refs Address Size Name 1 14 0xc0400000 709648 kernel 2 1 0xc0b0a000 13200 geom_mirror.ko 3 3 0xc0b1e000 33f90 zaptel.ko 4 1 0xc0b52000 6ad4 zaphfc.ko 5 1 0xc4e34000 16000 linux.ko 6 3 0xc4fc6000 52000 wanpipe.ko 7 2 0xc5018000 16000 sdladrv.ko 8 3 0xc502e000 6000 wanrouter.ko 9 1 0xc5042000 16000 wanpipe_lip.ko 10 1 0xc505c000 47000 wanec.ko Intially the system works quite well. 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.
