I can't guarantee nothing changed, but the system has been under normal callcenter operation 7 days a week with no issues. Customer doesn't even have root access to the server, nor they have a clue about Asterisk. All they do is unplug the E1 when it fails, then plug it back after issue gets solved.<div>
<br></div><div>One day I received an email where they began to notice "interference noise" over the calls. I first thought it was an analog gateway problem (the one agents use to connect to Asterisk), but later today when I was able to test the system the noise was coming from the E1 itself, as I made Elastix call my cell and playback a sound file and the noise was there. </div>
<div><br></div><div>Tomorrow I should be able to request they plug the E1 back again at about 20:00 GMT-6 and have a time window of about 40-60 min, in case you are interested in seeing the odd behaviour for yourself.</div>

Are you sure nothing changed? not even the card changed from pci slot?<br>
or adding a new hard drive or anything alike?<br>
<br>
Check if the card interface has overruns when that happens (ifconfig<br>
tells you that).<br>
