/mcpDescription Setting Enter 1 to 128 alphanumeric characters (a-z, A-Z, 0-9). The Instance ID identifies the user for the certificate operation. You can configure multiple connections (instances) of an application. To secure the connection between the application and CTIManager, ensure that each instance that runs on the application PC (for end users) or server (for application users) has a unique certificate. This field relates to the CAPF Profile Instance ID for Secure Connection to CTIManager service parameter that supports web services and applications. Instance ID From the drop-down list, choose one of the following options: • No Pending Operation—This message is displayed when no certificate operation is occurring. (default setting) • Install/Upgrade—This option installs a new certificate or upgrades an existing locally significant certificate for the application. Certificate Operation The authentication mode for the Install/Upgrade certificate operation specifies By Authentication String, which means CAPF installs, upgrades, or troubleshoots a locally significant certificate only when the user or administrator enters the CAPF authentication string in the JTAPI/TSP Preferences window. Authentication Mode To create your own authentication string, enter a unique string. Each string must contain 4 to 10 digits. To install or upgrade a locally significant certificate, the administrator must enter the authentication string in the JTAPI/TSP preferences GUI on the applicationPC. This string supports one-time use only; after you use the string for the instance, you cannot use it again. Authentication String To automatically generate an authentication string, click this button. The 4- to10-digit authentication string appears in the Authentication String field. Generate String From the drop-down list, choose the key size for the certificate. The default setting is 1024. The other option for key size is 512. Key generation, which is set at low priority, allows the application to function while the action occurs. Key generation may take up to 30 or more minutes. Key Size (bits) This field, which supports all certificate operations, specifies the date and time by which you must complete the operation. The values that are displayed apply for the first node. Use this setting with the CAPF Operation Expires in (days) enterprise parameter, which specifies the default number of days in which the certificate operation must be completed. You can update this parameter at any time. Operation Completes by This field displays the progress of the certificate operation, such as pending, failed, or successful. You cannot change the information that is displayed in this field.
