[asterisk-users] Static in Monitor recordings

[Adam Kavan]

I turned off hyper threading and it did not help, I also tried telling
it to record as gsm files but it still makes an awful noise.  Anyone
have any other ideas?

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.

	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.
