I have a production 2851 gateway with call manager 4.2.3. I have added a vic2-2fxs card to one of the slots, 0/2/0, and have done the "update / reset gateway" through ccm, and the "no mgcp / mgcp" commands on the router. However, the card does not register with call manager. Since this is an addition, do I have to use "ccm-manager config" ?
