Hiya,
Video conferencing is great in theory but I think hands on people prefer hands on teaching on service courses and face to face discussions. Thats in the nature of your typical service tech is hands on.
NHS IT policy restricts bandwidth and server space to its users. The use of streaming audio and video is banned in all our trusts hospitals. It would be worthwhile checking if this is national policy for NHS IT before going down this route.
Training and awareness sessions are always better face to face IMO. Video conferencing smacks of a company trying to avoid meeting (prospective) customers and reducing training costs and effort providing customer support.
Not so bad if any savings are passed on in reduced cost of spares training or product to the customer I suppose.
If technical training and safety awareness sessions were foc with no strings and NHS had access then it might catch on but it depends on what your selling and how it compares to the competitions products.
