Unified CM and CTI Manager Design Considerations

Configuring the Unified ICM Peripheral Gateway for CTI Manager
Redundancy

To enable Unified CM support for CTI Manager failover in a duplex Unified ICM Peripheral Gateway
model, perform the following steps:

Step 1

Create a Unified CM redundancy group, and add subscribers to the group. (Publishers and TFTP servers
should not be used for call processing, device registration, or CTI Manager use.)

Step 2

Designate two CTI Managers on different subscribers to be used for each side of the duplex Peripheral
Gateway (PG), one for PG Side A and one for PG Side B.

Step 3

Assign one of the CTI Managers to be the JTAPI service of the Unified CM PG Side A. (See

Figure 3-7

Note that the setup panel on the left is for Side A of the Peripheral Gateway. It points to the CCM1
subscriber and uses the PGUser CTI-enabled user account on the Unified CM cluster.

Step 4

Assign the second CTI Manager to be the JTAPI service of the Unified CM PG Side B. (See

Figure 3-7

Note that the setup panel on the right is for Side B of the Peripheral Gateway. It points to the CCM2
subscriber and uses the same PGUser CTI-enabled user account on the Unified CM cluster. Both sides
of the duplex PG pair must use the same JTAPI user in order to monitor the same devices from either
side of the PG pair.
