Bill, to close out this thread: After logging into your system, I'm nearly certain you'll need to contact Digium technical support for assistance if moving the card into a different system doesn't change the results. I ran the same commands I ran on your server on a test server of mine and this is what I would have expected on your server: $ cat system.em.conf span=1,0,0,esf,b8zs e&m=1-24 loadzone = us defaultzone = us $ modprobe --first-time wcte12xp vpmsupport=0 latency=6 debug=1 $ dahdi_cfg -c system.em.conf $ dahdi_maint -s 1 --loopback localhost Span 1: local host loopback ON $ patlooptest 1 -t 10 && patlooptest 1 -t 10 Using Timeout of 10 Seconds Going for it... Timeout achieved Ending Program Test ran 33 loops of 2039 bytes/loop with 0 errors Using Timeout of 10 Seconds Going for it... Timeout achieved Ending Program Test ran 34 loops of 2039 bytes/loop with 0 errors On your server this same sequence would produce repeated patloop errors even though there were not any indications in dmesg of latency bumps, which would be case if something else was preventing the wcte12xp interrupt service routine from running. The patlooptest errors would explain the bad audio you recorded with dahdi_monitor and the DTMF detection problems.
