Kevin, <br><br>Let's compare. Right now I am restarting asterisk when convenient every hour, and that's keeping the symptoms at bay. However if I let the problem get to the point that it won't take ANY incoming / outgoing calls then I cannot even initiate a restart from the CLI. I have to back all the way out of the CLI to the system prompt and actually call the init script to restart the asterisk service itself. Is this similar for you?<br>

<br>
I've never had problems with the circuit until I moved it from a standard
digium PRI card to a TDMoE device. <br>
<br>
Also, if I restart asterisk, all the b-channels come back. <br>
<br>
Thoughts?</span></font></p>

<p><font face="Times New Roman" size="3"><span style="font-size: 12pt;">You probably have noise on your T1 circuit, which is causing the PRI<br>
signalling to become corrupt. If this continues, expect that the T1
circuit<br>
will go down from time to time, for a few seconds each time. Your
solution is<br>
to call your telco and ask for a loopback test.<br>
