Do you think it is normal? Could be this values symptom of a problem on the server?
We have some voice quality problems in our voip network.

I have to say that this gateway at the moment is not assigned to perform transcoding (i'd like it did it since its is a good hardware) but this values seems strange to me. In others servers i have very minor values.

It is assigned to the last part of our voice network and it send traffic in alaw via sip to our isp.
Its load in not heavy, it never handles more than 20 simultaneously calls.

The machine is a 4 cpu Xeon(TM) CPU 3.06GHz with 2 Gb of ram one Wildcard TE405P quad-span T1/E1/J1 

Linux is a Debian 5

Linux gw-01 2.6.26-1-686 #1 SMP Fri Mar 13 18:08:45 UTC 2009 i686 GNU/Linux

Asterisk is

Asterisk 1.6.0.15 built by root @ gw-01 on a i686 running Linux on 2009-09-24 08:41:26 UTC

Dahdi is

(upgraded today to see changes)

Thanks for yours indications, regards
