I am using Cisco Unified Callmanager 4.1(3). My issue is, whille I am attempting to translfer a call to another extension in another cluster is failing and getting busy tone.
For example: I have a callManager cluster which have an intercluster trunk with another CCM cluster. While doing normal dialing, call connected without any issue. But, while transfering a call to the same extension in the other cluster, it gets busy tone. This is on net call transfer. I am able to transfer call to another extension range in the other cluster without any issue. Issue only for certail extension range in the other cluster. The route pattern to other cluster exension range is in the same partition and same routelist. Please help me to find a solution for this problem..
