UC500 Unknown signaling error.

I have replaced everything other than the UC500. I keep getting these two messages over and over.

*Jul 9 22:29:34.751: Unknown signaling debug message (ch=0):

0001 0001 **

*Jul 9 22:29:34.791: Unknown signaling debug message (ch=0):

0001 0000 **

They start right after I reload and say no.

Re: UC500 Unknown signaling error.

These errors are caused by the following bug -

CSCsk44000

Externally found severe defect: Resolved (R) UC520 error:Power alarm on DSP

channel ch=x is ON causes fxs port fail

This is resolved in 12.4(11)XW4 and higher.

Load 14.4.11XW8 code as this is the latest release for the UC520
