Zoom is a videoconferencing application that normally has free accounts available to use for unlimited meetings, but only allows for 40 minute meeting lengths; however, during this time, they are offering their professional accounts for free also. I like Zoom because it is super easy to setup, it works on almost any platform, it has higher video and audio quality than most, you can record your meetings, and it integrates into Canvas.
