Chapter 5 Configuring System Components
Configuring JTAPI Parameters (Cisco Unified Communications Manager Only)
Note To configure CTI ports for MWI, the Cisco Unified Communications Manager must have a CTI 
port that is assigned the DN you specify when you configure the CTI port, and the DN must be 
under the control of Cisco Unity Express JTAPI application user.
If an MWI port is configured on Cisco Unity Express but the DN is not in service, or 
Cisco
 Unity Express cannot register the port, no notifications are generated. If no MWI port is 
configured, Cisco Unity Express uses one of the CTI ports configured with the ctiports 
command.
Cisco Unified Communications Manager and Cisco Unity Express Version Compatibility
Depending on the version, Cisco Unity Express can be configured to work with different versions of 
Cisco Unified Communications Manager. For more information see the Cisco Unity Express 
Compatibility Matrix.
The following scenarios apply when installing Cisco Unity Express with a different version of 
Cisco Unified Communications Manager, or upgrading the Cisco Unified Communications Manager 
version:
  • By default, each version of Cisco Unity Express is set up to work with a specific version of Cisco 
Unified Communications Manager. Once you configure the IP Address or Hostname of the Cisco 
Unified Communications Manager, you must reload the Cisco
 Unity Express module for the 
configuration to take effect. After this reload, Cisco
 Unity Express automatically reloads again if the 
configured Cisco Unified Communications
 Manager version is different from the supported default 
version. 
  • If the Cisco Unified Communications Manager server being used by Cisco Unity Express is 
upgraded, Cisco
 Unity Express reloads and updates its system files to work with the new version of 
Cisco
 Unified Communications Manager. No further action from you is required.
Prerequisites
To use a separate CTI port for MWI, you must have 3.2 or later releases.
Required Data for This Procedure
The following information is required to configure the JTAPI parameters:
  • IP address or hostname for the primary, secondary, and tertiary Cisco Unified 
Communications
 Manager servers
  • JTAPI user ID and password from Cisco Unified Communications Manager. The password is case 
sensitive. These values must match the JTAPI user ID and password that were configured on 
Cisco
 Unified Communications Manager.
  • List of CTI ports
  • To use a separate CTI port for MWI, a list of DNs that are assigned on Cisco Unified 
Communications Manager and are under the control of Cisco Unity Express JTAPI application user.
