The retrieveCall activity is called to retrieve the call in a hold state to an active state. This activity uses the CallID and the DN properties to perform a retrieve call request to the CTI server.
If the call retrieval is successful released, then the state of the call is changed to active state. If the request is unsuccessful, then the CTI server will return an error to the CTI toolbar.
- Map the CallID and DN properties of the OpenCTI adapter page to the corresponding request parameters of the Pega Platform 8.6 integration connectors.
- Build a request appropriate for your connector.
- Invoke the appropriate request to the CTI server using Pega Platform 8.6 integration connector.
- Identify errors and handle it as discussed in Handling Errors.
