I want to know the answer to the following question:
What is one way that videocalling can be used?
All the background I'm provided with is that "Typical use of the various technologies described above include calling or conferencing on a one-on-one, one-to-many or many-to-many basis for personal, business, educational, deaf Video Relay Service and tele-medical, diagnostic and rehabilitative use or services.". Is that enough to answer the question?
Answer: no
