Tableau allows you to combine data from multiple sources and display it on visual dashboards. Your Delacon call data can be pushed to Tableau, via Google BigQuery.
Before connecting to Tableau, you will need to first set up your Delacon data in BigQuery. You can find out how to do that in our article Activating Delacon Call Data Transfer in BigQuery.
As soon as you have your Delacon data linked to BigQuery, you can display it in Tableau. Tableau have a guide to connecting their service to BigQuery, which you can find here.
