One great obstacle when you working oversea are that you never actually see your co workers face. Sure there is plenty off phone calls but conferencing can make it so much more pleasant from Thailand.
There is always more benefits to a video call then there is to a normal phone call and you can do some much move like show new products, take screen shoots, record the conversation, broadcast to others and much more. With the right equipment even slow internet connections can make your video conferencing calls a day to day tool that you can not manage with out.
Now when Thailand is soon get 3G and WIFI all over the country video calls from mobile phone is possible.
