I have a scenario that includes two CUCM clusters. DNs on one cluster may overlap DNs on the other. An Inter Cluster Trunk exists between the two clusters. A route pattern exists on each cluster that begins with a specific 2 digit code that routes calls for DNs on the other cluster to the ICT.
I use LDAP sync to provide user directory entries ( synced on the ipphone field ). I wish to create an additional LDAP Sync directory entry to create user records for the users of the other cluster, using a search base specific to their OU. However, when their ipphone fields are used to create user records, I need them to be pre-pended with the 2 digit code of the ICT so that when dialed from the directory, the calls will be routed to the ICT. How can I accomplish this?
