Hi,
Can't find the first bug mentioned, and second is "unreproducible" (that doesn't mean it isn't very real).
I would upgrade the router to latest 12.4 before contacting the TAC.

I've seen this error a few times - can you post sh diag and configuration?

Hi Johnny,
Seeing the same thing on 12.4(3g) 3845..
MGCP ISDN PRI.
All the other circuits on the box are working fine.
We see a DSP crash error message then the router reloads the dsp and restarts the voice port.
I'm suspecting hardware, but did you get any further with your investigation?
Cheers,
Tim.

If you are willing to continue in "good IOS hunting", try 12.4(3j), or 12.4(11)XJ4. Both are know to have stable ISDN, although admittedly MGCP is a different beast.
