JS API to read the driver phone number from device details page, I don't see it in the list of rest API's, can someone point me in the right direction?

I am trying to read the driver phone number so I can export them into an excel or txt file and not sure of the call to do this. For example: 

For MAC I use: mobicontrol.device.macAddress

FOr IP I use: mobicontrol.network.activeNetwork.ipAddresses

For Driver Phone Number: ??
