Web conferencing has become an increasingly desirable option for businesses that don't want to spend the time and money it takes to fly employees around the world for meetings that don't require face-to-face contact. Manufacturers such as eDial, Juniper Networks, Nortel Networks, and Polycom have begun selling Web conferencing server-based software systems that companies can run themselves on their internal network, dedicated servers, or network appliances. This approach enhances security, control over collaborative operations, and integration with existing communications infrastructures.
