Video conferencing through ISDN happens as you are able to integrate both analog or voice data together with digital data over the same network. This means you are able to encompass frame relay service for high speed data in large bursts.
This can also be done using your IP network which is very similar to how you are able to browse the web. In the US, more people use IP’s compared to ISDN but in Europe, this is the exact opposite because it happens to be much cheaper than IP’s.
When you are budgeting how much will be needed for video teleconferencing setup, you have to break down the fixed acquisition costs from the recurring costs. The fixed cost depends largely on how many units you will be ordering. There is also the license that you have to get that is $250 to $40,000 each and if you are a very large company, you might just exceed $100,000 per package since you also have to consider the hardware and software components needed.
Is it worth all that just to have video conferencing? A lot of people say yes because their employees are more productive, decisions are made quickly and the company saves money.
In fact, private companies are not the only one using it as the government, the education and the healthcare sector have also taken advantage of this to conduct hearings, teach children and help patients.
