RE: [cisco-voip] CUCM trunk connection

Hi All

Does anyone has some training material about SME, SAF and CCD. As this new
features on CUCM 8.X, I don't have much knowledge on this topic.

Thanks

Best Regards

David

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.

Subject: [cisco-voip] 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
