Has anyone used the OurFamilyWizard video and/or call features? What is recorded?

My ex started to refuse cell phone contact when the children are at their home. A suggestion was to use the OurFamilyWizard video and/or call functions.

We use OurfamilyWizard for everything else like parenting calendar, parent-to-parent messaging, and check-ins for exchanges.

Any advice or feedback?
