Hi Karen, Could you please post the config and sh version (I presume you are using your own rack)
In MGCP the D-Channel is backhauled to CM, and the moment connection to CCM is lost, it should remove "isdn bind-l3" command for the proper SRST operation, however upon detection of the WAN connection back to CCM, this command should automatically be added back, interestingly its not happening. A bug, may be?

More over, I think we shall need to verify if the configuration has the ccm-manager switchback. Could you please post your config ?
