Pega's documentation says that "Phone numbers are configured in Pega rules or are retrieved by integrating with an external system.".
On Configuring the CTI link there is only option to map a phone book which has to be created separately and the numbers needs to be entered manually. Is there any OOTB option to fetch the phone number from a DB table directly, so that all newly added numbers gets picked up by the phone book automatically?
But this is the reason I am confused. If there is no such option how can Pega mention that option in the document. Even any other non OOTB option is also appreciated but I could not find a way to configure the same.
