Original Caller ID cannot be display while transferring a call through ICT

[kinman-wong]

Dear Expert,

I found that when I transfer a call through Intercluster Trunk (ICT) the original caller ID cannot be displayed. The scenario as below:

Phone 1 --> CUCM 1 --ICT--> CUCM A --> Phone A. Phone A can see the call is from Phone 1. Then Phone A transfer the call to Phone 2

Phone A --> CUCM A --ICT--> CUCM 1 --> Phone 2. In that case Phone 2 see the call si from Phone A instead of Phone 1.

Is there any way can keep the original caller ID through ICT?

Thanks & regards,

Ben

have you set the 'Calling Party Selection' to Originator on the ICT?

Yes, it is Originator.

is that the blind transfer or consultive transfer?

does the phone-2 display phone-A number after the call is connected or only during the alerting state?

[kinman-wong]

It should be consultive transfer but normal user behavior is press the 2nd transfer key follow with the dialed extension without waiting phone-2 user answer the phone. The calling ID is phone-a after connected
