I can answer to myself:
Modify the config.yml to:
- kind: Callerid
connector: csv
connector_options:
property_map:
- property: __key__
external_name: key
export_transform: transform.key_id_or_name_as_string
- property: queue
external_name: queue
import_transform:
transform.none_if_empty(transform.create_foreign_key('Queue'))
export_transform: transform.key_id_or_name_as_string
- property: num
external_name: num
