[cisco-voip] 7936 firmware issues

[george.hendrix at l-3com.com]

I'm actually trying to put these on an CCM 8.5 cluster.  They will register all day with the 4.2 cluster, but not with the 8.5 cluster.  However, the phones won't upgrade at all on either cluster.  From what I can tell, about the only thing to do is to RMA the phones.  I found the following on the 7936:

I believe the 7936 loads were also subject to this bug:
CSCec20531    7935 upgrade process unnecessarily complicated

I believe the symptoms of that issue included the load showing blank.

Hi All,

  We have a handful of 7936 phones that are giving us a problem.  We have about five 7936 phones that show nothing for the phone load.  I have noted the following:

1.       The phones will register to our CCM 4.2 cluster
2.       The phones wont upgrade to ANY firmware, old or new.
3.       The phone load shown on the phones' admin webpage are blank.

Any ideas of how to force these to boot to the default internal load.

Thanks,
Bill Hendrix
