asterisk users - Apr 2006 - call center running Asterisk - sound quality - critical!

Hi,

I am using Asterisk for a call center on a Dual Xeon machine..

I currently have 

109 active channels
53 active calls

Every body is complaining about quality and cpu is around 80% idle.

Is there any tuning I can do???

Besides that, Asterisk normally goes down once or twice per day...

Thank you
Dov

>From what you say it sounds that the problem is not with asteisk, but
the way it's configured. Asterisk should *never* go down that often.
Asterisk as a normal PBX should run without a restart for as long as
there is power to the box, in the case of a call center if I would
hear of a restart once a week I would accept it, but still would look
for ways of improving it beyond that.

You complain about call quality, what type of phones are thes? What
codec? are they all local?

Dov,
Do you have any quality of service capability on your data network for
prioritising voice?  With that volume of calls it could be a network load
issue if your cpu seems to be fine.
What kind of interface are you using to the PSTN?

sounds like a standard mutex deadlocks ???
you mean the cli is unresponsive, no new calls are accepted
OR
do you mean a real core dump thats much easier to resolve

just get a bt & post to the end less bugs at bugs.digium.com
you might also want to peak in on icd at openpbx.org no deadlock there in
call center in europe
running 300 pls agent with icd on amd opitron box
see cypromis on irc on openpbx if you want more details

are you sure you have your T1 sync setup correctly?
rtfm on zaptel.conf

If you don't want to worry about * handling the full recording of all
traffic, you can potentially do this on a separate server on the RTP
path using http://www.oreka.org.
