Call Transfer is not working

Unanswered Question
Jul 29th, 2010

Dear All

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..

Best Regards,


I have this problem too.

Hi, what type of codec is configured beetween clusters? If it is g729, I guess you have a codec issue between clusters. Plase share the config of your regions and if it is possible try a g711 call.

My default Internal codec is G.711 and intercluster trunk using G.729. I am able to call to some range of extensions Eg: 9XXX. But I agm not able tocall 7XXX. which have the same routelist configured.
