Video calls are getting a lot better, with higher resolution cameras built into mobile devices and higher bandwidth networks.
To that end, I am curious, who is using video calls to help their techs in the field. Often, a junior to mid level person will be on site, facing a problem they cannot solve on their own. Describing it verbally can be challenging, whereas a live video session could give a more senior employee the information they need to help solve the problem.
I could see this saving quite a lot of money and hassle.
So who's doing it? Any success? Any issues in doing this?
