Group,
    I was making a network change last night and had an odd result.  I had a
2821 with an MGCP PRI and 2 WIC cards with PtP T1s.  I took the WIC cards
out and installed them in a 1760 to separate the WAN function from the VG
functions.  After taking out the 2 WICs I applied the following changes to
the 2821 VG....

As you can see I did not take out the "isdn bind-l3 ccm-manager" command
from the ser0/2/0:23 interface.  The only thing that I can think may have
done this was the Lo0 commands that I added for h323 binding.

Anyone have an answer as to why this would have happened and made for an
uneasy change?
