When you have a driver on the phone, you can search for their phone number in Tenstreet. If it doesn't show, you can click on "Start a Phone App" in the top ribbon and do a full IntelliApp on the phone
This will save the driver in your dashboard and allow you to do an app transfer or do follow-ups while tracking.
You could ALSO send them your link by doing a "Quick Add Lead" in the top left. Make sure you click the checkbox for "Send Applicant Link to Intelliapp"
