In order to use the Live Audio, you will need to add your cell phone as the authorized number (this is called the SOS number).
You will only need to set this up once.
This video explains how to set the SOS number.
The easiest way to set your cellphone as the authorized number is to use the Logistimatics mobile app. Inside the app, go to Commands > + > Set SOS Numbers
You can also set the SOS number via text message. Text the following to your tracker’s phone number:
SOS,A,YourCellphoneNumber# (No spaces!)
After the SOS number has been set, you can use the app to initiate listening. You can also press and hold the button on the tracker which will call the SOS number. Note: if you want to turn this behavior off, you can. Just choose "Disable SOS button" from Commands.
After you have set your SOS number, you can listen in by going to Commands > New Command > Have Tracker Call me. Note that you can also just call your tracker's phone number to initiate a two-way conversation.
