Hi Chris, what version of Skuid are you using? Are you building in api v1 or v2?
Since this functionality is coming from another managed package, you will need to build the click to call functionality out within Skuid. Depending on the component you're using, there's options to include a template field and configure on click actions using the action framework. The Fastcall click to call functionality may be included as a data source type action or you may have to tap into that functionality some other way.
It looks like you're new here. If you want to get involved, click one of these buttons!
