Synopsis
When you pick up a telephone, you expect to converse in a clear and understandable way. The ubiquitous public system telephone network provides this service. A voice over IP system needs to provide the same. Anything less would provide an excuse to avoid the technology. The public Internet is notoriously haphazard. Watching a web page stall as it loads is a fine example of the pitfalls of this complex technology. Quality of service is an issue with Voice over IP and is usually listed as one factor in the slow adoption of the technology.
