CUCM 4.2 Pub and SUB at main location additional Sub deployed at remote location. Also at remote location we have another CM Cluster deployed and connected via NGC intercluster Trunk. We are trying to migrate all the remote gateways and endpoints to our Main CM cluster. When we configure 1st remote location gateway to remote Sub from Main CM cluster in-bound calls to remote site work fine, outbound calls through remote connected gateway will not work (receiving reorder) Have configured gateway as H 323 and MGCP with same results. When we switch remote gateway back to original remote CM Cluster everything works just fine. Checked CSS and works OK with other gateway in route list.
