Intercluster trunk and Display (Internal Caller ID) transmission

[marcel.schmidt]

HI everybody,

we have 2 callmanagers connected via intercluster trunk. How can I transmit the Display (Internal Caller ID) over the intercluster trunk? Does it work?

Can anybody tell me how, if?

Regards

Marcel

Yes this sould work, it may have to do with CSS, and Partitions, also check you ICTrunk configurations as well.

Marcel,

Are you using different versions of Call Manager? If so this may be your problem because from version 3.1 name display has been supported for inter-cluster calls.

Make sure that under your trunk configuration on both sides you have "Display IE Delivery" checkbox checked.

You can also do a detailed CCM trace, and use Q.931 translator (found in cisco\bin) to decode the H.225 messages in the trace. The decoder will show you whether CCM is sending/receiving the Display IE.
