If you’ve never used online teleconferencing before, it's basically an app on your phone that lets you send voice notes to each other in real time as well as text messages, images and videos.
I am able to use any of the following apps – Voxer, Teams, Skype, Facebook Messenger, WhatsApp, Telegram.
You choose the medium that suits you!
It’s perfect for bouncing ideas or getting feedback/advice on something in a super flexible way where you don’t have to be seated in front of (or tied to) a screen/laptop to do so.
