If you use www.datablaze.com for GPS tracking for your techs they offer a "Uber Style" site where you can watch the tech's progress as they approach your location. We are able to include a link on our Dispatched portion of ID181 (notice to say tech is on the way) that includes a link saying something like "Click here to track our technician in real time".
The link is only live while the tech is dispatched. Email firstname.lastname@example.org to get started.
Clicking the bottom right arrow will get you call details.
If your having issues with the CEO Juice emails not sending tracking information after you've already worked with Datablaze to use this feature:
When a Tech Enroute link is created, it also generates a note under the service call in the service call list. The Note Type is either ZCJ_DBZ181 or CEO Juice ID 181 / Datablaze Live URL and should have the URL in the note itself. If there is no note to be found, then likely the call was dispatched too soon after it was reassigned, so the tracking note didn't have time to be created in the call.
