CCM Cluster Redundancy Design

Hi all,

Under CCM redundancy (active + standby), I have some questions as follows:

1. How the user get the coprate directory when the primany CM is down??

2. How the personal directory / address book works if the primary CM is down?

3. How the Extension Mobility achieve if EM redundancy is needed.

Generally, if the XML service involves the primary IP address, how the resiliance is achieved? by DNS, or other means?

4. Apart from the CCM basic config, will the system parameters are syn thr. this (1+1) cluster? In my finding, at least I found the CDR parameters are not syn thr. these 2 CM servers.

Thanks & Regards,
