Standard ECMA-269
Services for Computer Supported Telecommunications
Applications (CSTA) Phase III
7th edition (December 2006)
This Standard specifies an interface and services between two entities that request and provide communication services (e.g. Applications, middleware, PBX, IP-PBX, Softswitch, phone, softphone, software devices).
CSTA operates with existing interfaces, so that differences among various existing interfaces are hidden.
Services defined in this Standard allow functional integration between a computing network and a telecommunications network.
This Standard is part of a suite of CSTA Standards and Technical Reports. See documentation.
