We are running asterisk and we have people stating that the calls sound choppy. We are running Ulaw and asterisk 1.4.2 running CentOS 4.5 running kernal 2.6.9.
System load is very low never hitting above 10% on processor or mem. we have 15,000 rpm scsi and its on a gigibit network.
It happens when they call outside lines and a few say even inside the network. We also have reports of 1 or 2 dropped calls.
Only the people on the other end of the call can hear it we can not.
