Extension Mobility Cross Cluster (EMCC) – Configuration

What is Extension Mobility Cross Cluster?  Extension Mobility enables you to login within the cluster (intra-cluster) whereas Extension Mobility Cross Cluster (EMCC) enables you to login from a home cluster to a phone at visiting cluster (inter-cluster). This was introduced in 8.X Version or later.
Recently i have configured EMCC and i came across many issues but however the lab was successful. I couldn’t test the full functionality as i had Cisco IP Communicator which is not supported as per Cisco. I have tested the registration process from Home Cluster to Visiting Cluster successfully.
To start with the configuration, we need to ensure that we have a checklist ready so that the configuration is not missed out as the configuration is quite vast.
