</div>...This can mean a TON of things... You're goign to see this alert if<br>
your GW ungesisters from your CCM. That could easily be due to a<br>
network issue. Its entirely possible that your interface is bouncing<br>
at one layer or another when it unregisters or re-registers with your<br>
CCM, that could explain your controller errors. We need to see what's<br>
happening first. Is the GW losing registration with the CCM for a<br>
network or software-related reason, or is the actual T1 interface<br>
bouncing, or is there a different issues thats just causing a problem<br>
with the q.931 signaling.<br>
<br>
we need:<br>
debug mgcp packet<br>
debug isdn q931<br>
debug ccm-manager backhaul events<br>
debug ccm-manager config-download all<br>
<br>
...and anythign that appears in syslog, such as interface protocol<br>
state changes (int x is up down etc)<br>
<br>
...begging before and ending after the occurrence of one of the<br>
D-Channel OOS events.<br>
