[cisco-voip] CCM Clustering IP Block

[Kristján Ólafur Eðvarðsson]

As long the round trip time is not exceeding 40 ms cause that can
Casuse problmes with Clustering CCM servers. And crossing that latency is not supported by 
Cisco. This is case of SQL replication issues. And it is some problems with SQL 
If if the latency is higher than 40 ms rount-trip (20 ms each way)

If you are adding CCM servers to other sites. You might want to consider adding another cluster
On the remote site and to Trunking beetween clusters. That means of course different Databases
On each Cluster. This of course depends on the scale of your installation.

There is no problem with CallManagers being on separate subnets, provided that ip routing between the subnets is configured.

Hi All,

Has anybody tried adding a callmanager subscriber that is not within the existing cluster's IP block ? I was wondering if this would create problems to the clustered system.

Thanks,
Ryan
