Dialogic conferencing boards provide application developers an optimal feature set for chat line applications. The on-board Active Talker feature, which determines which conferees are talking at any given time, significantly reduces time to market for applications requiring active talker information. Time to market is further reduced with applications already written for the MSI/SC station/conferencing boards since the API commands are easily converted. Most importantly, since tone capability and conferencing are handled in a single slot, Dialogic conferencing boards offer a very affordable solution. They deliver full-duplex conferencing, tone-out support, and high-quality audio on an open PC-based platform at a low price.Dialogic gives you access to the lucrative business conferencing market, which continues to expand as it moves from proprietary-based systems to open system-based components and is now expanding to the Internet. Many more technologies are available with open system integration than with proprietary systems.
