Yes, using debug mgcp packet I see the gateway send a RSIP, the backup CUCM sends it's RQNT, I can then see the AUEP for each channel, and the corresponding AUCX for the active channel. A show ccm-manager shows it as registered to the backup. The call is eventually disconnected when the gateway sends a DLCX to call manager after about 15 seconds. I am testing by shuting down the primary cucm call manager service.
