CTI connectivity issue with undefined/invalid VDN in monitor



Computer telephony integration (CTI) link stays in the Connecting state and a fully connected state is not established.

On configuring the CTI link instance with undefined or invalid VDN in the list to monitor, the connection is unstable and logs off automatically. However, the agents are able to login to the CTI instance.

Root Cause

A defect in Pegasystems’ code or rules.
