<P><FONT SIZE=2 FACE="Arial">I got experienced an extremely strange issue with my Call Managers and I was looking to see if anyone had any insight. </FONT></P>
<P><FONT SIZE=2 FACE="Arial">This morning we started getting busy signals on some of our inbound calls. These were sporadic. I tried looking at the real-time monitoring tool but I couldn't tell if the PRIs were being oversubscribed. We have 6 PRIs coming into 2 separate 6608s. Then without warning, 3 of the sites that are on this cluster lost all dial tone. We didn't even have internal dial tone. When you lifted the receiver there was nothing. Only one site was still up and they were homed to a different server.</FONT></P>
<P><FONT SIZE=2 FACE="Arial">We rebooted the publisher and the two subscribers that displayed the problem and everything started working normally. I had no errors in my app log on any of the servers and it didnt show any of the phones come unregistered. I am at a loss. I have never seen anything like this before. </FONT></P>
<P><FONT SIZE=2 FACE="Arial">Has anyone ever seen this? Any ideas as to what caused it? I didn't see any errors on the switchports either.</FONT>
