ABSTRACT
Forum) specifies software interfaces used throughout their vision of a computer telephony architectural model based upon open, shared resource servers. The foundation for the ECTF’s software standards is the S. 100 media-and switching-services API that allows resources to be shared in CT servers. For client/server systems, the ECTF’s S.200 mediaservices transport-protocol interface provides client inter communication with the server. If a manufacturer happens to supply a product that encompasses both a client and serv er, it is not restricted to using S.200 but can instead use its own proprietary protocol. The ECTF’s S.300 service-provider interface permits the telephony server to interchangeably use resources from different vendors as they work together in sharing CT resources.. The S.900 administrative-services interface includes functionality for managing the server’s configuration, faults, performance, security, and accounting.
