The CTI Link engine runs as a set of Java objects on the application server. You can configure the number of Java threads that each CTI Link uses.

To configure the number of threads, perform the following steps:

1. In the header of Dev Studio, click ConfigureChannel ServicesPega CallAdministration & Configuration.

2. Open the CTI Link that you want to run on the specific nodes.

3. On the CTI Link rule form, switch to the Advanced tab. Under the Engine Threads section, configure the minimum and maximum threads that are used by the CTI Link.

4. Save the rule. Your changes take effect the next time the CTI link is started.

   Note: If your deployment has a large number of users on a node using the same CTI Link, increase the maximum number of threads. Each Java thread processes CTI events for several Pega Platform operators. Configure how many users will share a Java thread. For most environments, a Java thread can process events for up to 50 operators.
