[cisco-voip] busting SBC

What version of CCM and what IOS on router/gw?

Can you post snippet of config with mgcp and
ccm-manager commands from router/gw config, and
dial-peers?

The admin down in logs sent previously indicated it
was MGCP if no human was doing shutdown commands. MGCP
shutsdown interfaces while it is applying
configuration it downloaded from CCM. That may happen
when router loses connectivity to CCM for some reason
or another, also there have been some MGCP bugs/issues
that could be effecting you perhaps.
