Release Notes for Cisco CallManager Release 3.0(10)
78-13493-02
The following example highlights the difference:
The Cisco IP Interactive Voice Response System typically opens several CTI
route points and CTI ports; it will always open a single CTI connection to a
Cisco CallManager in the cluster. The 400 connection limit applies to the CTI
connection and not the CTI ports or route points.
BAT Reinstallation
Administrators must reinstall BAT after installing Cisco CallManager 3.0(5a)
because of a change made to the database.
IOS Version
The Cisco CallManager Release 3.0(5a) was tested with IOS 12.1(3x)XI2.
Intercluster Trunk Configuration
An intercluster trunk, a virtual h.323 gateway, interlinks Cisco CallManagers in
different clusters. Beginning with Cisco CallManager Release 3.0(4), intercluster
trunks were configured differently. To ensure redundancy and proper failover
operation, each cluster must configure an intercluster trunk to each
Cisco CallManager in the remote cluster with which it shares a link.
For example, assume that you are configuring intercluster trunks among three
Cisco CallManager clusters: Cluster-1, Cluster-2, and Cluster-3C:
•
Cluster-1 has three Cisco CallManagers: CCM-A, CCM-B, and CCM-C.
•
Cluster-2 has two Cisco CallManagers: CCM-D and CCM-E.
•
Cluster-3 has two Cisco CallManagers: CCM-F and CCM-G.
In the preceding scenario, you must configure 14 intercluster trunks to ensure
redundancy:
•
Cluster-1 configures 4 intercluster trunks (to CCM-D and CCM-E in
Cluster-2 and CCM-F and CCM-G in Cluster-3).
