This chapter of the SRND should be a good read for you.

I think the goal is ultimately end to end sip anymore. If you have SIP, sccp, etc phones, the interconnect between cm nodes should not matter. The big advantage like Matthew said is the ability to propagate presence information between clusters.
 
If you have numerous clusters, then it probably deserves a conversation of  Callmanager SME in between all your clusters to simplify your design at each cluster.

I have used SIP for intercluster in the past as it allowed presence information to be shared. I think that answers 1 and 2, not sure about 3.

Hi All
 
For CUCM cluster interconnection, we also use inter-cluster trunk on the CUCM.
 
For my client standard, they use SIP trunk for the CUCM cluster inter-connection. I have some question about this design.
 
1.        Is it possible to use SIP trunk to the CUCM interconnection.
2.        If the design is correct, what is the advantage for using SIP trunk instead of inter-cluster trunk.
3.        As my client has Cisco SIP phone, is it the reason they need SIP trunk to the CUCM interconnection.
 
Thanks
Best Regards
David
