CUCM trunk connection

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
