During one of the ‘Remote Work Focus Group’ meetings, concerns were raised about the use of personal cell phones for OCG business.   While it’s undeniable that cell phones can make remote work easier, their use may not be ideal from a work/life balance or privacy standpoint.  Below are some alternatives, options and ideas around remote work communications.

Microsoft Teams Calls

Microsoft Teams Calls has all the functionality you expect from a traditional desk phone including hold and transfer, call forwarding, voicemail, and blocking unwanted callers.

You can make ‘Audio Calls’ from Zoom – just turn off your camera.  The software is free and ubiquitous.  Simply start a new meeting and send the link to your attendee(s).


  • This is a great choice for communicating with just about anyone. 
  • See the general notes below about using Zoom with Controlled Unclassified Information (CUI).
  • Not for use when discussing CUI or Export Controls.  See below.

Personal Cell Phone Tips

The below are not recommendations, but options if you choose to use your personal cell phone for OCG business.

General Notes and Caveats

Use a land line, cell phone or in-person meetings for:

  • Conversations concerning details related to controlled unclassified information (e.g. the actual data, anything marked CUI by government, whatever is controlled).  Do not use Teams or Zoom.
  • Conversations concerning details related to export control issues (what, who, technology).  Do not use Teams or Zoom.
  • Google Voice should not be used for any work communication because of security concerns, per Scott Maize in CU Boulder’s Research Cybersecurity.
