Google Voice

This allows educators the privacy of connecting with students and caregivers without having to give out their phone number. Both texting and voice features are available. In many cases, Google Voice will transcribe your phone messages. You can either have the calls to your Voice phone number transferred to your personal number or you can listen to them online at your convenience. Users can also make calls to parents and families from a computer screen using Voice, providing they have a microphone attached to the computer and that it is configured properly.

Must be set up with a private Google account. Not available via your TPS account.
