Hi. We upgraded from CM 3.0(9) to CM 3.1.1 over the weekend and switched our Voice Gateway from a 3640 to the WS-6608-E1 blade on a Cat 6000. All seemed well on Friday night, however, Monday morning problems started popping up as calls in progress would immediately get dropped at random. Not even does it drop all calls in progress! Only certain calls. I read on the forum archives where Dave suggested to someone with a similar problem to register all ports with CM, even as MTP, so I did that. All ports now except for 1, which keeps saying "Port Host processor not online" are registered. I did this about 1 hour ago, but the problem is still popping up. The error we are receiving in the CM App Error log is:
Dchannel0 OS-D channel out of service
Explanation: Indicated D channel has gone out of service
we are also getting many phones that are producing a
"Device Unregistered / REason: 8 " message and somehow unregistering and re-registering themselves?
My clock setting on the Gateway is set to "Network".
Does anyone have any ideas or have experience with this problem? I would be extrememly appreciative as my boss is upset b/c his calls keep getting cut off!
thanks! - jason
