title: Can Twilio provide any location data for incoming calls or sms?
body: <p>I'm setting up a new time clock-type application for one of my clients. We need the worker's location whenever the worker calls in to confirm they are at the proper job site.</p>
  
  <p>So I found some services like this one <a href="http://timesheetmobile.com/" rel="nofollow">http://timesheetmobile.com/</a> which claim to be able to:  "Unlike other location applications that run on the phone, Timesheet Mobile utilizes the carrier's secure network (cell towers) to identify the location of the employee's phone." They claim this works with any cellphone - no app required.</p>
  
  <p>Is this kind of location data available from Twilio for either incoming calls or SMS?</p>
