Sounds like a poweredge server and the 2850 we have...hyperthreading has caused
all kinds of crazy stuff...and turning it off just in grub.conf doesn't
solve it until it is turned off in the bios.

Subject: [asterisk-users] Static in Monitor recordings
I am running Asterisk 1.2.9.1 in a call center with 26 agents placing outbound
calls using SIP soft phones going out a Diginum 4 port T1 card (All 4 spans have
PRI t1's).
All of the calls run through
[macro-record-call]
exten =>
s,1,Monitor(wav,${ARG1}-${CALLERIDNUM}-${DATETIME:0:11}-${DATETIME:12:2}-${DATETIME:15:2},mb)
and this works fairly well, however several times a day I get recordings with
static in them. It sounds like a corrupted wav file, with noise in it all over
the place. It is obvious from the conversations occurring in the recording that
the other people involved in the call do not hear any of the static, so I assume
that it is coming from the recordings.
Also, our QA people are using ChanSpy to listen into these calls and tell me
that they can hear the static as well, but I have not been able to verify there
claims.
Last night I tried using MixMonitor instead of just Monitor and QA claims that
there were no problems with the sound, but my Asterisk server kept crashing and
I assume that MixMonitor was at fault (the crashes went away as soon as I
changed back to regular Monitor).
Does anyone know why this might be happening?
On the whole I am having no stability problems other than last night with
MixMonitor. I eventually want to scale my deployment up toa little over 200
agents and I want to make sure I get this figured out while I still am using my
fairly small testing population.
My server is a Dell with 2 X Intel(R) Xeon(TM) CPU 3.20GHz with hyperthreading
turned on and 4 GM of RAM and my storage is a SCSI hardware raid card, pointing
to a mirror.
Any help you can give me would be greatly appreciated.
