We have Two CCM (6.1)Clusters. Cluster A and Cluster B. Calls b/w the Clusters are working through ICT non-gatekeepers. However we would like to setup failover that if long distance PRI failed in ClusterA, we would like to route those calls to Cluster B long distance Gateway by adding ICT to Long Distance Route List with less priority. We have access code to dial long distance and discard digits predot within cluster and access code for inter-cluster calls.
Is this possible?
Any assistance/guidance would be highly appreciated....THANKS
